摘要
在考虑成本收益基础上构建有利于可再生能源发展的电价机制,对促进中国能源结构转型升级内在动力的提升具有重要意义.本文建立了整体电力市场机制模型,包含中长期交易市场的电量出清模型、日前市场的增量现货市场模型和实时市场的平衡调度模型,并在实时平衡调度模型中设置目标函数为系统成本最小、弃风量最小双目标函数.在IEEE 6节点标准测试系统里,计算了不同电价机制下的电力市场交易结果,研究发现,与系统边际电价相比,边际节点电价出清的电价机制下风电企业利润更高,弃风率更低.因此,该机制更有利于风电发展;同时,当系统收益一定时,边际节点电价机制能使电力系统总成本最小.
It is important to study the suitable pricing mechanism based on benefit-cost analysis,which is a guarantee to realize the goal of China’s energy system upgrade.Two kinds of models are studied:The medium-and-long term trading market clearing model,the day-ahead incremental spot market model.A bi-objective function is established in the real-time equilibrium dispatch model:One objective is to realize the least system cost,and the other is to realize the least amount of discarded wind power.An electricity market trading simulation in the IEEE 6-bus standard test system is conducted.We find that,the locational marginal price(LMP) mechanism is beneficial to the development of renewable energy and power industry.The results also indicate that,the node marginal price mechanism can minimize the total cost of the power system when system benefit is identified.
