随着户用光伏在配电网中的占比日益提升,原有低压减载方案已经体现出一定的不适用性。为解决高密度户用光伏并网后的低压减载问题,提出了基于多智能体技术的高密度户用光伏智能减载控制方法。首先,分析了光伏的有功-无功调压原理。然后,基于多智能体技术提出智能减载单元分层协同控制策略;最终,利用改进粒子群算法实现智能减载控制。仿真结果表明,所提的方法能在一定程度上实现智能减载,减小电压偏移,具有一定的可靠性和实用性。

With the increasing proportion of household photovoltaics in the distribution network,the original low-voltage load shedding scheme has shown certain inapplicability.In order to solve the problem of low-voltage load shedding after high-density residential photovoltaics were connected to the grid,an intelligent load shedding control method for high-density residential photovoltaics based on multi-agent technology was proposed.Firstly,the principle of active-reactive voltage regulation of photovoltaics was analyzed.then,based on multi-agent technology,a layered cooperative control strategy of intelligent load shedding unit was put forward.finally,the improved particle swarm algorithm was used to realize intelligent load shedding control.Simulation results show that the proposed method can achieve intelligent load shedding and reduce voltage offset to a certain extent,which has certain reliability and practicability.
