Under the background of China's ultra-high voltage power grid construction and West-to-East power transmission project, over-generation operation in valley-load period has become one of the most severe problems. In order to solve the problem of valley load over-generation in regional power systems, the partly deregulated market environment is introduced, which helps allocate peak regulation resources among provincial grids in the region. This paper develops a regional down-regulation market, and proposes a price iterative two-layer optimization model aiming on the stability of the load distributing process and the maximization of the profits of region-dispatched plants. The model has been implemented to the peak regulation of East China Power Grid. The numerical results show that the proposed method is effective for the valley load over-generation problem in China.
