摘要
电力市场环境下,发电方、输电方和负荷方成为各自独立的经济实体。各方存在的风险因素都可能导致系统对旋转备用的需求,因此购买旋转备用的费用应由电力市场中存在风险因素的各方分摊。利用旋转备用损益期望值来评价旋转备用对具有风险因素的各市场参与方的价值,并按比例分摊旋转备用费用。最后,研究了改进算法效率的方法。算例分析验证了该旋转备用费用分摊方法的公平性、合理性和较好的可靠性激励作用。
In electricity market environment, power generation, transmission and consumption become self- governed economy entities. The risk elements for all market partners can result in the need for spinning reserve in power system. So the spinning reserve cost should be allocated among all three partners having risk elements. The spinning reserve＇s value for all the market partners having risk elements was evaluated by using the expectation of spinning reserve＇s gain or loss, and the reserve cost was allocated in proportion according to the spinning reserve＇s value for all the market partners. The means for improving the algorithm＇s efficiency was also discussed. Case study shows the rationality and equity of presented method, and its effect on encouraging all partners to raise the reliability of power system is also validated.
