摘要
根据实际工程需求,将统一潮流控制器(Unified Power Flow Controller,UPFC)的拓扑结构进行变换。将UPFC系统的串联换流器和并联换流器接在不同的线路中,为了提高串联侧的输电能力,提出一种可再生能源对UPFC系统提供有功功率支持的方案。由于可再生能源的不确定性,为了系统的安全和稳定,可再生能源提供的功率先由电池储能进行存储,再做接入;对含新型UPFC拓扑结构的输电系统进行数学建模,以传输功率最大化为目标函数,通过遗传算法进行求解;最后通过算例仿真验证所提方案的正确性和有效性。
According to the actual engineering requirements,the topology of unified power flow controller(UPFC)is changed.Firstly,the series converter and parallel converter of UPFC are connected in different lines.Then,in order to improve the transmission capacity of the series side,a scheme of renewable energy to provide effective support for UPFC system is proposed.Because of the uncertainties of renewable energy,in order to ensure the safety and stability of the system,the power provided by renewable energy is stored by battery energy and then accessed.The transmission system with a new UPFC topology is modeled mathematically,and the transmission power is maximized as the objective function,which is solved by genetic algorithm.Finally,the correctness and effectiveness of the proposed scheme are verified by numerical simulation.
