In electricity market environment, power generation, transmission and consumption become self-governed economy entities. The change of supply and demand for these market partners can result in the need for automatic generation control (AGC) ancillary service. So the AGC cost should be allocated among them. In our country, the amount of AGC is ascertained on the base of the control area, it is difficult...
With the development of electric market, the interconnecting electric power system, whose purposes gradually transfer to market. And how to obtain the biggest economic performance becomes the main contents of study, and this brings up more and more high request for the problem solving. With consideration of the characteristics, the article introduces the genetic algorithm to the study of economic...
Real-time price is the fulcrum of competitive electricity market, which is also an effective way to achieve optimal allocation of power market resources. Firstly, this paper builds a mathematical model about the competition of wholesale market and retail market; And then, it builds an incentive model about the influence of Growth of real-time price consumers on generation capacity investment; Finally,...
In the environment of electricity market , the reflection of reserve on the reliability of electrical system is very visibly and reserve has couple with the main energy market. It seems very important to research equilibrium relationship of reserve market. The text presents a model that on the condition of opportunity cost and price elasticity of demand, formulates a model of the reserve equilibrium...
A number of Distributed Energy Resources (DER) of various technologies with various operating pattern and availability can be integrated in a Virtual Power Plant (VPP). Some of the Distributed Generators (DGs), those are dispatchable and have high capacity, can individually participate in the power market but they may choose VPP if they hope to reach a higher benefit in the power market through VPP...
This paper develops bidding strategy for operating pumped storage power plant in a combined pool-bilateral market. 1/0/-1 mixed-integer programming model to account discrete tri-state operation of pumped storage plant is developed and multi-looping sequential optimization approach is used to solve the problem. Considering realistic case study, operating strategies for the pumped storage plant are...
The share of distributed generator (DG) in the power system generation is increasingly grown up. Due to the effects of DG on technical operation of the network and also considering the rapid extension of power market in the world wide, it is necessary to contemplate both technical aspect of network operation and market transactions in DG operation. Through the concept of virtual power plant (VPP),...
Based on the two principles that guaranteeing power system safe and reliable operation and minimizing the total cost of power generation, this paper established a capacity assignment model among the different kinds of power generators. According this model, arranging each kind of power generators has practical instruction significance for power generators constructing during the development of our...
In a restructured power system, the problem of maintenance scheduling is different from the traditional centralized power system. This paper is demonstrated how GENCOs (generating companies) in a competitive environment prepare the maintenance schedule of their facilities. Taking into account that in the new structure the main purposes of GENCOs are selling electricity as much as possible and making...
