The integration of wind energy (WE) with flexible AC transmission system (FACTS) devices into the grid to improve grid performance is one of the latest advances in renewable energy (RE) technology. This work proposes the optimal placement and size of a WE, a doubly-fed induction generator (DFIG) with two of FACTS controller, viz. thyristor-controlled series compensator (TCSC) static var compensator (SVC). The goal is to maximize system bus load (Max. LBS) and minimize active power loss (Min. Ploss) by satisfying various safety and stability constraints. Newton Raphson\'s power flow study involving TCSC, SVC, and DFIG is a bi-objective that meets multiple constraints: lines, generation, voltage limits, and small signal stability. A variant of the genetic algorithm, non-dominated sorting GA II (NSGA-II), was applied to solve the contradictory bi-objective optimization problem. A modified standard and practical test system, the IEEE 14-bus and the Indonesia Java Bali 24-bus, integr...

This study discusses the optimal placement of one type of WECS, namely the doubly-fed induction generator (DFIG) with a series and a shunt-FACTS control device called unified power flow controller (UPFC). The DFIG and UPFC connected grid dynamic perfor mance improvement with a maximum load bus system scenario. The optimal placement of DFIG and UPFC on the grid is formulated as a multi - objective problem, namely maximizing load bus system (Max. LBS) while minimizing active power loss (Min.

Saluran transmisi merupakan saluran untuk menyalurkan energi listrik dari pembangkit ke konsumen. Lokasi menara saluran transmisi pada suatu daerah tertentu sangat menentukan banyaknya gangguan yang terjadi akibat sambaran petir. Besar sambaran petir langsung pada menara atau kawat tanah dapat mengakibatkan back flashover pada isolator. Besarnya arus sambaran petir dan besarnya nilai resistansi pentanahan menara dapat mempengaruhi besarnya tegangan gangguan yang terjadi. Pada skripsi ini untuk mengurangi besar dampak tegangan gangguan yaitu dengan memperkecil nilai pentanahan menara. Dengan menambah panjang elektroda pentanahan dapat memperkecil nilai pentanahan menara. Dan dengan program PSCAD dapat mengetahui besar lonjakan gelombang sebelum dan sesudah merubah nilai resistansi menara. Arus sambaran petir 180 kA dapat mengakibatkan backflashover, karena nilai tegangan crossarm melebihi tegangan lompatan api yaitu sebesar 1324,31 kV sedangkan batas tegangan lompatan api sebesar 131...

Increased awareness about climate change and the demand for green energy has led to the proliferation of renewable energy generating units (REG) in power systems. The need for better system reliability requires utilities to connect these generating sources close to the load. One of the main problems with sources such as solar, wind turbines, fuel cells, and micro-hydro turbines is their integration into the existing power grid without significantly redesigning the system. An efficient method of solving this is to integrate these units into a microgrid. This method is the first step in the development of a smart grid. This study will study the effect of microgrid penetration controllers to achieve safe maximum instantaneous microgrid energy penetration. The microgrid models involved in this study include wind energy, solar energy, and energy storage integrated into the grid system. The Double Fed Induction Generator (DFIG) type wind turbine used is integrated into the dynamic model o...

Electricity is generated from different sources such as thermal, coal, nuclear, solar, wind and so on. The generated electricity is connected to grids for further use. If forecast from renewable energy is available, then the utilization of non-renewable resources could be reduced and so the cost and impact on environment can also be reduced through optimized grid balancing. Solar power is one of the renewable power sources in focus due to the upgradation of photovoltaic technologies and simplified system components. But, the yield out of photovoltaic cells could be strongly influenced by factors such as shadow, cloud, rain, dust, temperature, humidity, panel angle, seasonal effects, panel efficiency and so on. Hence, all these factors need to be considered for forecasting solar power. In this chapter, the ‘Adaptive Curve Fitting’ model is introduced for forecasting solar power, wherein the majority of the algorithm is based on mathematical modelling which considers clear sky referen...

Gangguan voltage sag merupakan satu masalah dari power quality yang mana bisa berdampak buruk pada konsumen dan industri. Karena dapat berakibat miss operation pada beberapa peralatan industri atau peratan sensitif terhadap voltage sag. Masalah tersebut dapat diatasi dengan metode injeksi tegangan menggunakan peralatan elektronika daya yaitu Dynamic Volatge Restorer (DVR).

A significant power system occurrence, the voltage stability of the system due to the integration of new generation into the grid, has been investigated in this paper by using a continuous power flow (CPF) method consisting of successive load flows. Since one of the solutions to prevent voltage instability causing voltage collapse is by controlling the system's reactive power limit, in this study the effect of placing the Shunt FACTS controller, Static Var Compensator (SVC), into the grid against the voltage stability has been investigated. An accurate controller model supported by the PSAT (Power System Analysis Tool) is used to study the voltage stability of the system. The effectiveness of the proposed method has been examined on the 16-bus Bali practical test system due to the integration of the Celukan Bawang Power Station and by detecting the bifurcation point. Moreover, improving voltage magnitude profile and line power loss (Ploss) of the system are also investigated.

The integration of distributed generators (DGs) with flexible alternating current transmission systems (FACTS) can improve the performance of the grid system. In this study, we determine the location and optimal size of one type of DG, based on wind energy, with a shunt-FACTS control device called a static var compensator (SVC). The voltage profile is increase and the power loss reduced due to an improvement in performance from the maximizing load bus system scenario. Newton-Raphson power flow with a wind turbine generator (WTG) and SVC are formulated as a multi-objective problem called MLB system and minimizing system power loss (Ploss) by satisfying various system constraints, namely the loading limits, generation limits, voltage limits, and the small-signal stability. A variant of the genetic algorithm, called the non-dominated sorting genetic algorithm II (NSGA-II), is used to solve these conflicting multi-objective optimization problems.

In a power system, the reactive power imbalance is related to the stability of the static voltage because the injection of reactive power that the bus receives from the system determines the bus's capability in the system. Rapid increases in real and reactive power losses occur as the system approaches the voltage drop point or the maximum load point. It is necessary to support local and adequate reactive power to avoid system leading to be voltage collapse. This study analyzes the improvement of the margin of static voltage stability using one type of modern control equipment of shunt flexible AC transmission system (FACTS), namely the static var compensator (SVC). The controller's representations are used in the continuation power flow (CPF) process to study static voltage stability. The proposed method's effectiveness has been investigated using a practical test system, namely the Bali 16-bus system, to increase the system loading capacity. The simulation was carried ...

A robust sequential primal-dual linear programming formulation for reactive power optimization is developed and discussed in this paper. The algorithm has the characteristic that no approximations or complicate control logic are required in the basic Sequential Linear Programming (SLP) formulation as used by other SLP algorithms reported in the literature. Transmission loss minimization is used as the primary objective. A secondary feasibility improvement objective is used which results in better feasible solution in comparison with the loss minimization objective especially when the initial base case has over voltages. Modification in the proposed method to obtain the limited amount and limited movement of controller solution for real time application is also presented. The algorithm has been tested on Ward and Hale 6-Bus system.

Background: Modern power system operations often faced with very unsafe conditions caused by voltage stability problems. If the problem cannot be controlled with the right method, then a cascade system can occur. This condition can cause a voltage reduction drastically and leads to a power outage. Objective: The Fast Voltage Stability Index (FVSI) and Line Stability Factor (LQP) implemented in this study. Both indices can determine the optimal location and capacity of Wind Energy (WE) into the grid to anticipate a sustained increase in load.

In recent decades, one of the main management’s concerns of professional engineers is the optimal integration of various types of renewable energy to the grid. This paper discusses the optimal allocation of one type of renewable energy i.e. wind turbine to the grid for enhancing network’s performance. A multi-objective function is used as indexes of the system’s performance, such as increasing system loadability and minimizing the loss of real power transmission line by considering security and stability of systems’ constraints viz.: voltage and line margins, and eigenvalues as well which is representing as small signal stability. To solve the optimization problems, a new method has been developed using a novel variant of the Genetic Algorithm (GA), specifically known as Non-dominated Sorting Genetic Algorithm II (NSGA-II). Whereas the Fuzzy-based mechanism is used to support the decision makers prefer the best compromise solution from the Pareto front. The effectiveness of the deve...
