Many system operators around the world are challenged by the problems associated with integrating these intermittent resources into the grid. As one of the potential solutions, demand response (DR) is expected to play a major role for mitigating integration issues of intermittent renewable energy resources. In this context, this paper proposes a DR program which helps to integrate wind power by reshaping the load of the system. The DR program provides a framework to procure load reduction from DR resources in the wholesale energy market. The participants in the program submit their offer packages to provide load reduction in the day-ahead energy market. A day-ahead network-constrained market clearing formulation is also proposed which considers the load reduction provided by the DR program participants as an energy market commodity. The proposed method, which is in the mixed-integer linear programming format, determines commitment state of generating units, schedules the energy and spinning reserve provided by generating units, and schedules the load reduction provided by the DR program participants. To reveal the features of the proposed method, several numerical studies are conducted on the IEEE-RTS. The results presented indicate that integrating load reduction in the energy market provides a powerful tool to selectively modify the system load to support wind power integration, while making significant economic and technical benefits for the system.

Conventional reliability information about power system operation only considered health and risk states which were not often adequate criteria both in system planning and utilization.

The day-ahead distribution system operation problem is formulated as a mixed-integer linear programming (MILP) model, in which profit of the distribution system operator (DSO) from serving local loads is maximized. The impact of time-varying electricity rates on local loads is determined based on the estimated price elasticity of the customers and the historical consumption data. The customers' consumption behaviors in the absence of time-varying electricity rates are captured in terms of the customer baseline load (CBL). The proposed model is applied to a 33-bus distribution system. Numerous studies are conducted in order to analyze the impacts of incorporating time-of-use (TOU), critical peak pricing (CPP), and real-time pricing (RTP) on the operation decisions, load profile, profit of distribution system operator (DSO), and customers' bill.

With significant penetration of PEVs in the near future, the concept introduced in literatures as Vehicle to Grid (V2G) will be practically possible. The V2G concept eases the integration of renewable energy resources into power system and gives a new force to the inevitable move towards power generation by clean energy resources. Therefore, trends in utilizing energy stored in PEVs will bring undeniable economic and environmental benefits. The V2G aspect has been the field of many research works in the last few years. This paper intends to present a study conducted to reveal the different features of V2G in power system. In this study, V2G applications are investigated from the perspective of power system as well as electric market. In addition, V2G capabilities are discussed to utilize renewable energy resources as secure power sources and to provide ancillary services. Specifically, the paper has detailed the importance of smart parking lots, their opportunities and challenges in relieving V2G difficulties and improving its utilization. In order to clarify different issues, the authors present practical analyses which are results of a loss optimization problem in a residential power grid. From a realistic standpoint, this work has tried to identify the major barriers towards making V2G practical and addresses remarks which will make V2G concept feasible as fast and simply as possible.

The procedure to accomplish this cost allocation is designated as 'loss cost allocation'(LCA). So far, a number of LCA methods have been proposed for transmission networks. A few papers have compared different loss allocation methods, which are the methods which ...

The proposed framework is divided into corrective control (CC) and preventive control (PC) subproblems. The CC subproblem deals with the condition that a power system encounters voltage instability as a result of severe contingencies. This control is merely devised to restore system stability. The PC subproblem is brought up when the system operates in a stable region but its LM is ...
