摘要：Increasing proportion of nuclear power plants (NPPs) and prominent disparity of peak load and valley load in electric power industry has caused great difficulties to peak load regulation. It is necessary for NPPs to participate in the peak load regulation in valley load period. Equivalent peak load regulation (EPLR) of NPPs can be realized by taking advantage of flexible power units or energy storage equipment. In this paper, a two-stage dispatch strategy is proposed to realize EPLR of NPPs as well as to ensure the peak load regulation enthusiasm of power generation groups (PGGs) with flexible power equipment. Benefits of different PGGs are calculated and compensation is considered. A computation of combined heat and power system is analyzed to illustrate the performance of the dispatch strategy. The results show that the benefits of PGGs can be ensured when the EPLR of NPP is achieved. Copyright 2018 Elsevier Ltd. All rights reserved.
