Modeling and Analysis of Daily Generation Schedule Considering the Coexistence of Planned Electricity and Market Trading Electricity

Abstract

With the continuous promotion of China's electricity market-oriented reform, some provinces and cities will gradually introduce market-oriented trading means on the basis of traditional generation schedule. In this context, how to establish the daily generation schedule model considering planned and trading electricity is an urgent problem to be solved. In this paper, a model of daily generation schedule that combines planned electricity decomposition and Nash equilibrium of market trading electricity is established, in which the existing mode of generation schedule is taken into account. By means of solving the model, the daily generation plan was evaluated in two aspects of economy and security, by studying the impact of different market openness. An example simulation of a provincial power grid in East China is given to analyze the impacts of different market trading electricity proportion on the generation cost and power shortage expectation of the whole system, and verify rationality and effectiveness of the proposed model.
