. The ambitious KSA 2030 Vision has among others targeted the deployment of renewable energies to meet KSA’s primary electric load in the residential, commercial, and industrial sectors. Within this framework, the authors have evaluated the economic and technical feasibility of using a combination of solar PV systems and central energy storage systems in the health sectors. The combination of the two sources means reducing gas emissions, and increasing the instantaneous power from renewable energy sources while using energy storage to counterattack the intermittency of solar PV energy that is known to cause stability issues for the grid. In addition, it reduces the dependency on standby diesel generators that emit high pollution levels. The paper addresses the available energy storage devices and the design of a hybrid solar PV system combined with battery-stored energy. Through the study, it was found that up to 15 percent of the electric consumption can be provided by the solar PV system. It was found that the cost of energy competes with conventional electricity. In addition, the cost of storage devices has a significant impact on the cost of energy. Moreover, low payback periods were obtained for some systems.

SummaryFog computing allows for local data processing at the edge of the network. This allows for reduced link delays between mobile users and access points. Here, fog nodes are collocated with radio remote heads (RRHs) to provide local processing capabilities, that is, creating fog radio access network (F‐RAN) that can support ultralow latency for cellular networks that operate on millimeter wave (mmWave) bands. Here, mobile stations (MS) demand various network functions (NFs) that correspond to different service requests. Hence, it is critical to study function popularity and allow content caching at the F‐RAN. Given the limited resources at the fog nodes, it is important to efficiently manage the resources to improve network operations and enhance the capacity at reduced delays and cost. Therefore, caching in mmWave F‐RAN requires node allocation that can accommodate the highest number of cached functions. Hence, this paper proposes a novel node placement scheme that leverages Nelder–Mead meta‐heuristic. Results show that the proposed scheme yields in reduced delay, cost, and power and energy consumption.

Fog-radio access networks (F-RANs) alleviate fronthaul delays for cellular networks as compared to their cloud counterparts. This allows them to be suitable solutions for networks that demand low propagation delays. Namely, they are suitable for millimeter wave (mmWave) operations that suffer from short propagation distances and possess a poor scattering environment (low channel ranks). The F-RAN here is comprised of fog nodes that are collocated with radio remote heads (RRHs) to provide local processing capabilities for mobile station (MS) terminals. These terminals demand various network functions (NFs) that correspond to different service requests. Now, provisioning these NFs on the fog nodes also yields service delays due to the requirement for service migration from the cloud, i.e., offloading to the fog nodes. One solution to reduce this service delay is to provide cached copies of popular NFs in advance. Hence, it is critical to study function popularity and allow for content...

Due to global warming, governments around the world are focusing on renewable energy as the main source of energy. Gulf countries in particular, are focusing on solar energy due to its abundance and the gulf geolocation that allows the installation of ambitious solar photovoltaic (PV) energy systems and replace conventional power plants. In order to maximize energy extraction from the sun, solar power operators need to constantly monitor key solar PV parameters such as panel temperature, solar irradiation, voltage and current in order to detect abnormalities in the PV system operation and take the necessary actions to keep the PV system performance at its maximum. However, monitoring such parameters on-site is exhausting and expensive. Moreover, remote monitoring for solar PV systems is a more attractive solution once the data collection, processing and transmission become faster and less expensive. This paper describes the design of a low-cost remote monitoring system intended for ...

The Maximum Power Point Tracking controller (MPPT) is a key element in Photovoltaic systems (PV) since it allows maintaining the PV operating point at its maximum under different temperatures and sunlight irradiations. Metaheuristic algorithms such as the ant colony optimization (ACO) are adopted and have shown their superiority to many other techniques. The perturb and observe (P&O) algorithm is a simple and efficient technique, and is one of the most commonly employed MPPT schemes for PV power generation systems. Which executed by manipulating direct duty ratio of the boost converter. P&O method miserably fails to recognize various MPPT controllers. This paper proposes ACO technique to solve real-life problems.

Large and small single-phase and three-phase induction motors are commonly used in industrial applications. The present work represents an attempt towards the design of a high accuracy system for the measurement of fractional horsepower (FHP) induction motor losses and efficiency. The calorimeter designed and built is capable of measuring heat losses of up to 1 kW with an overall accuracy better than 3%. During all tests, ambient temperature, humidity, motor speed and motor frame temperature were recorded using precise digital instruments. The inlet, outlet temperatures and resulting losses were recorded automatically using a high accuracy 12-bit data acquisition system. The preliminary results obtained demonstrate the suitability of the designed calorimeter for the accurate measurement of losses in FHP induction motors.

This paper is devoted to the state of the art in photovoltaic (PV) conversion chains and their architectures. Two major characteristics are considered to classify these chains. These are the galvanic isolation and the number of stages; characteristics generally localized around the DC-AC converter (inverter) at the end of the PV conversion chain. Therefore, this paper deals with a comprehensive review of the different inverter topologies that can be integrated into PV conversion chains, distinguishing between the transformer based and the transformer-less conversion chains. The paper demonstrates that to this date, transformer-based inverters are very common and widely used, have a long record of accomplishment as a component of solar energy systems, in particular for residential applications because of their greater efficiency, smaller size, and lower costs. Nevertheless, transformer-less chains are touted with some problems and shortcomings. Moreover, solar energy storage devices...

The aim of this study is to develop a procedure for the design of institutional grid-connected solar PV (Photovoltaic) systems using campus buildings’ roofs and car parking shades. This procedure was developed and validated in the design of a single phase 10 kW solar photovoltaic system at King Faisal University, Al Hofuf, and Kingdom of Saudi Arabia. The method consists of 12 steps including resources assessment, site selection; grid access and requirements; supporting structure and roof type, area, orientation, strength and shading. Once the roof and supporting structure are selected, the facility layout, required grounding and lightning protection are finalized according to IEC Standards. The final stage of the design is to testing the facility. The 10 kW facility has been operating since March 2014. The results for 2014 and 2015 indicate that daily energy production were slightly below the rated values and in some months of the years, the station better that the simulated performance using PVSyst software. The lightning protection, system was considered in the study and subsequent modification would be necessary in the near future.

The integration of the PV systems into the electric power grid has many challenges. One of these challenges is to disconnect PV inverters from the grid due to excessive DC-link voltage. This may lead to stability problems in the power network. To avoid the dc-link overvoltage problem, passive and active Low Voltage Ride-Through (LVRT) control strategies have been proposed in literature. This paper focusses on the performance comparison of passive LVRT schemes such as the DC Braking Chopper (BC) with active LVRT scheme, ‘Divert the MPPT operation’ (D-MPPT) during the fault. The performance of various LVRT strategies has been evaluated through simulation of a grid connected PV system connected with multi-machine power system.

This paper proposes a simple numerical method to determine the optimal location of a distributed generation (DG) within the distribution network. The main objective of this work is to find the optimal number, the type, the size and the bus location of DG that would enhance the voltage levels and reduce the power losses of the distribution network. Initially, load flow, using Newton Raphson Method, was carried out without DG to identify the weak busses on the distribution network, then, the load flow simulation was carried out with the DG units being connected on the identified weak busses to evaluated the impact of the DG units on the voltage profile and power losses. The test case IEEE 30 bus system is modeled using standard load flow software. Simulation results with the DG units show improvement in terms of voltage profile enhancement and power losses reduction. Test results indicate that the load flow studies yield positive impact on the 30-bus distribution systems. The maximum power losses reduction was as high as 15.30% and the bus voltage improvement reached 8.72 % for optimally placed single DG and 13.89% for 4 DG units.

This book demonstrates that lightning is an important factor in designing electric power systems. Lightning causes outages of transmission and distribution lines, damage of renewable energy systems and railroad equipment. The book illustrates protection design and devices to reduce lightning outages. Further reduction of such outages is possible by understanding lightning phenomenon and thunderstorm frequencies. Such information is of a great importance in the design of transmission lines, renewable resources and railroad systems. Establishing Isokeraunic level and ground flash density (GFD) maps in Saudi Arabia would improve lightning protection practices for utilities, elevated structures, industrial installations such as oil refineries and other sensitive assets.

This dissertation introduces a new planning and operational tool to integrate photovoltaic (PV) systems into the utility's generation mix. It is recognized that much of the existing research concentrated on the central PV system, its operations, and long-term planning with PV system and concluded that technical problems in PV operation will override any value or credit that can be earned by a PV system and that existing breakeven capital costs make large-scale PV penetration limited. First of all, in most cases, PV power was subtracted from the utility load with the expectation that conventional generation would meet the load. This approach is valid for small penetration levels and for PV facilities connected near the load centers. Second, PV system was studied on a case-by-case basis. This made the interactions between the PV systems and conventional power systems not well known to the operator in the dispatch center on one hand, and to the PV system manufacturer, on the other hand. In addition, several constraints such as thermal generation ramping capabilities, energy costs, tie-line interchange, spinning reserve requirements, hydro availability and generating capacity, and pumped-storage scheduling are not adequately represented in this process. These are real problems and their solutions are sought in this dissertation. Finally, the value of PV systems does not lie only in serving load, but also in reducing problems associated with emissions. It is felt that a comprehensive methodology that would take into account the PV system characteristics and the forth mentioned constraints, as well as more global penetration is developed. The proposed methodology is designed to handle load dynamics and PV fluctuations, so as to minimize operational problems. The objective of this study is to determine the economic and operational impacts when large photovoltaic systems are incorporated into the electric utility generation mix. The proposed methodology handles combustion turbines, hydro and pumped-storage hydro power systems. Performance analysis shows that hydro availability, generation mix and characteristics, PV power output dynamics and performance, time of the year, and energy costs influence the economic and operational impacts of large-scale PV generation. Results show that while hydro dispatching increases acceptable PV penetration levels, generation mix and energy costs influence the breakeven capital cost. According to this study, for a 10 percent PV penetration level (1200 MW) and high energy costs, the breakeven capital cost is 968/kW and 1200/kW for Richmond (Virginia) and Raleigh (North Carolina), respectively. This corresponds to an energy cost of 3.20 and 3.00 cents/kWh for Richmond and Raleigh.

ABSTRACT When a galvanic connection between the grid and the PV array exists, a common-mode voltage exists which generates a common-mode currents. These common-mode currents may produce electromagnetic interferences, grid current distortion and additional losses in the system. Therefore, to avoid the leakage currents penalizing transformerless power chains, it is worth focusing topologies which do not generate common-mode currents. Some topologies available in the market touch more or less such a crucial requirement. This is said, a small room for improvement still exists. The aim of this work is to focus on recently developed topologies which do not generate common-mode voltage. It was shown that the HERIC topology does not generate common-mode voltage with high efficiency. The focus also will be on different ways to reduce harmonics in the output inverter waveform and to maximize the PV cells output power.

In Oman, the economy is shifting from oil exportation to a diversified economy. Also, as the growing population is seeking for a better quality of life, the electricity demand is increasing. However, there is a decline of gas resources, mostly used in the electric power generation, and a need to participate in the world efforts to mitigate climate change. To cope with these issues, the government triggered renewable energy pilot projects in rural areas. To enhance the efficiency of such projects in rural Oman, a strategic techno-economic analysis of these projects is performed to assess the techno-economic feasibility of utilizing such renewable systems to support the existing diesel-based generation system in rural areas. Simulation results using HOMER 2.19 for different geographical rural areas in Oman indicate that the renewable systems can displace diesel generation significantly and the economical benefits of the resulting hybrid systems depended on load and renewable energy resources.

On the other hand, the galvanic connection between the DC source and the grid generates leakage current through the earth parasitic capacitance.

ABSTRACT This paper deals with a novel transformerless inverter topology having high efficiency, low leakage current and no zero crossing distortions are encountered. In fact, the proposed topology is based on the conventional full bridge topology with an extra AC bypass branch to short circuit the load when the zero voltage of the control is applied. In this way, the current returning from the filtering circuit finds its path through the extra branch during the freewheeling period and remains at the AC side. This would increase the efficiency and decrease the leakage current. The control strategy of the proposed topology is based on a low cost microcontroller interfaced to two drivers to step up the MOSFETs gate voltages. The proposed inverter and its control strategy were implemented and promising results were obtained.
