摘　　要：针对我国区域电力市场中普遍存在由于省间经济发展不平衡而导致的发电成本省间差异较大的问题,基于差异性电力租金理论,以地理位置差别和优势产生的差异性电力租金为税源,向低成本省的发电机组征收区域电力平等基金税,建立考虑发电成本省间差异的区域电力市场竞价机制。算例分析表明,该机制可以提高发电成本较高省的机组出力水平和市场占有率,在一定程度上保护了发电成本较高省机组的市场竞争力,实现了不同省的同类型发电机组之间的公平竞争。There is a common problem in China＇s regional electricity market, i.e. the inter-provincial differences in costs of power generation as a result of the unbalanced economic development between provinces, which is an important topic required to be effectively solved for building regional electricity market. Based on the theory of differential power rent, this paper takes the differential power rent caused by differences in geographical locations and advantages as the rent sources, levies taxes of regional electricity equalization fund on the generating units in low-cost provinces, and constructs the bidding mechanism in regional electricity market considering the inter-provincial differences in costs of power generation. The analysis of numerical examples based on genetic algorithm shows that, this mechanism can enhance the output level of generating units and market share in provinces with the higher cost of power generation, and to a certain extent, it protects the generating units in provinces with high cost of power generation to keep their market competitiveness and achieves a fair competition between the generating units of the same type in different provinces.
