首先提出一种新型的考虑有功源(active power，AP)的统一潮流控制器(unified power flow controller，UPFC) UPFC-AP，该有功源从可再生能源发电获取能量，同时使用储能电池组作为储能装置；然后提出了该UPFC-AP的优化设计方案，该优化设计能同时实现两个目标：AP的最优容量和最小化功率传输角。通过优化设计，得到了UPFC-AP的可行工作区域(feasible operating regime，FOR)。使用FOR和经济调度策略，推导得出了上游电源和AP输出功率的最优经济调度策略。在此基础上，提出了最优负荷跟踪机制，同时实现了最经济的上游电源和AP的功率调度，且使功率传输角最小，最后通过仿真实例验证了所提方案的有效性。

A unified power flow controller (UPFC) incorporated with a battery energy storage system at DC side was examined. The battery system forms an active power (AP) source. The design of the UPFC-AP was formulated as an optimization problem in which practical operating constraints of the network and that of the UPFC-AP were taken into consideration. A feasible operating regime was obtained, within which the range of the AP output power that can be dispatched for given load demand was prescribed. The application of a proposed economic dispatch strategy results in an optimal load tracking scheme, the effectiveness of which is demonstrated through numerical examples.
