【摘要】：在可再生能源渗透率日益提高的背景下,为了促进优质灵活调节电源在市场环境下的发展,以电力市场的运行特征和实际发展需求为依据,综合考虑机组调节性能和调节效果,提出基于AHP的主能量市场绩效评价体系,兼顾灵活性和经济性的要求,设计差异化的主能量市场出清机制,并以系统运行成本最小化为目标,构建基于绩效的主能量市场与备用市场联合优化出清模型,通过与传统出清模式的对比分析,来验证该发电出清模式的有效性,最后分析可再生能源占比对运行结果的影响。算例结果表明,新的市场机制能综合考虑性能与成本进行电力市场出清,起到了有效进行资源优化配置、引导灵活性电源投资的作用。
[Abstract]:Under the background of increasing renewable energy permeability, in order to promote the development of high quality and flexible regulating power supply in the market environment, it is based on the operation characteristics and actual development demand of electricity market. Considering the performance and effect of unit regulation, a performance evaluation system of main energy market based on AHP is put forward, which takes into account the requirements of flexibility and economy, and designs a differentiated main energy market clearing mechanism. Aiming at minimizing the operating cost of the system, a performance-based optimization model of the primary energy market and the reserve market is constructed, which is compared with the traditional clearing model. Finally, the effect of the proportion of renewable energy on the operation results is analyzed. The results show that the new market mechanism can comprehensively consider the performance and cost of the electricity market clearing. It plays an effective role in optimizing the allocation of resources and guiding the investment of flexible power supply.
