摘要
随着需求响应与交直流配网不断发展,未来的配电网将出现电源侧分布式电源大量接入、电网侧直流配电方式兴起以及用户侧电力市场竞争性放开的发展态势。结合未来交直流配网中可能存在的可控元件和需求响应负荷,提出一种考虑需求响应的调度策略,其中可控元件包括:传统发电机、分布式电源和可控换流器等,充分挖掘交直配网的灵活性与需求响应相结合的潜力。以10节点交直流配网为算例,研究所提调度策略的经济性和消纳分布式电源(distributedgeneration,DG)的能力。
With the development of demand response and AC/DC distribution network,there will be plenty of distributed generators at the power supply side,a rise of DC power supply mode and opening of the electric market at the user side.A power dispatch strategy is proposed which takes into account the demand response and controllable elements in AC/DC distribution network such as traditional generator,distributed generator,converter,and so on.Taking 10-node AC/DC distribution network for case study,the economics and ability to absorb distributed generator of proposed strategy is studied.
