Study on joint optimization of power market clearing considering operation mode adjustment

In the context of the new round of power market reform in China, the construction of the spot and peak shaving market of electric power is being carried out in an orderly manner, and market clearing is the foundation and core of market development. Aiming at the problem that the restriction of the existing market clearing algorithm on the section limit of the power grid is not completely combined with the actual structure of the power grid, this paper mainly studies a market clearing algorithm for spot and auxiliary services considering the matching of the actual operation mode and the limit of the power grid. This method uses the combination of the section limit and the structure of the power grid to realize the market clearing, operation mode and section The organic coupling and step-by-step iteration of quota ensure the enforceability of market clearing results and the continuity of operation mode. Finally, based on the actual operation rules of central China regional market, the effectiveness and correctness of the joint solution method of market clearing and quota matching are verified by the actual quotation of generation side market members and the actual structure of power grid.
