摘要(Abstract):

在高比例强不确定性新能源接入的背景下,新能源场站与储能电站的协同合作日益密切。针对新能源场站与储能电站间分布自治决策的特点,以储能充放电功率为共享变量,采用基于交替方向乘子算法的分解协同机制,建立计及新能源不确定性的两运营商分布式协同优化模型,通过少量多次的信息迭代,得到分布式框架下的最优储能充放电策略。利用华北地区某小型综合能源系统数据,对比所提算法与集中式算法的计算结果,验证了所提算法的有效性和适用性。
New energy stations and energy storage power stations are working in closer cooperation in the context of a high proportion of new energy access with high uncertainty. Given the characteristics of distributed autonomous decision-making between new energy stations and energy storage power stations,a decomposition collaborative mechanism based on the alternating direction method of multipliers(ADMM)is used to establish a distributed collaborative optimization model of two operators considering the uncertainty of new energy. The optimal energy storage charging and discharging strategy under the distributed framework is obtained through few information iterations.The effectiveness and applicability of the proposed algorithm are verified by comparing the computational results of the proposed algorithm with those of the centralized algorithm using data from a small integrated energy system in North China.
