摘要
风光出力的随机性与反调峰特性增加了电网对新能源的消纳难度。利用源侧、荷侧的灵活可调节特性,设计源荷双边参与规则,引导源荷进行跨时间的双向功率协调以支撑清洁能源高效消纳。首先,梳理源荷双边参与的基本原则与原理,明确交易主体、品种以及模式并设计其参与规则。然后,基于源荷双边参与规则,构建计及源荷双边参与的日前能量与备用联合优化调度模型,在促进新能源消纳的同时降低工业用户用电成本。其次,针对多场景混合整数规划的求解难题,采用改进的渐进式对冲分解算法进行求解,通过启发式的变量“固定-筛选-松弛”,保证模型的收敛性。最后,基于IEEE 118系统进行算例分析,验证了所提能量与备用联合出清模型在促进新能源消纳方面的有效性。
The randomness and anti-peak shaving characteristics of wind and solar output make it more difficult for the power grid to absorb renewable generation.Using the flexible and adjustable characteristics of the source side and the load side,the bilateral participation rules of source and load are designed to guide the source and load to carry out bidirectional power coordination across time to support the efficient consumption of renewable energy.First,the basic rules and principles of bilateral participation of the source-load are sorted out,transaction subjects,varieties and models are clarified,and their participation rules are designed.Secondly,according to the bilateral participation rules of source and load,a joint optimal dispatch model of day-ahead energy and reserve is constructed taking into account the bilateral participation of source-load,so as to help the consumption of renewable energy and reduce the electricity cost of industrial users.Thirdly,to solve the problem of multi-scenario mixed integer programming,an improved progressive hedging decomposition algorithm is used to solve the problem,and the convergence of the model is ensured through the heuristic variable"fix-screen-relax".Finally,an example analysis is carried out on the basis of the IEEE 118-node system,which verifies the effectiveness of the proposed joint clearing model of energy and reserve in promoting energy consumption.
