Co-optimization Clearing Model for Energy and Primary Frequency Control Reserve Markets

摘要

The co-optimization of energy market and reserve market can achieve the richest economic benefits. However, only considering the reserve capacity demand cannot ensure the system frequency security. Based on the ancillary service markets in the countries with mature electricity markets, a co-optimal unit commitment model for energy and reserve markets with the primary frequency regulation ancillary service is proposed, which can promote the system frequency stability. Then this nonlinear problem is decomposed into a two-stage mixed integer linear programming problem by the L-shape method to be solved. Finally, the simulation results indicate the effectiveness and economy of the model.
