基于可调负荷的电网运行优化策略研究

Research on power grid operation optimization strategy based on adjustable load

为进一步加强智能电网运行调控,提出一种基于可调负荷的运行优化策略。其中,考虑到传统负荷调控未考虑约束条件的问题,构建含供电约束的实时分布式可调负荷控制算法,从而对某一时刻接入电网的可调负荷进行实时控制,让电力总负荷变化曲线地向电网供电功率曲线逼近。验结果表明:本研究构建的算法可使总负荷功率曲线无限逼近计划供电功率曲线;当t=12,负荷调度得到的用电功率与总负荷功率之间的绝对差值维持在[0,3]kW之间,而不包含供电约束的实时分布式可调负荷控制算法的绝对差值波动范围在[1,6]之间。由此得出,引入包含约束条件的负荷调度效果更好。

To further strengthen the operation and regulation of smart grids,an operation optimization strategy based on adjustable loads is proposed.Among them,considering the problem that traditional load regulation does not consider constraint conditions,a real-time distributed adjustable load control algorithm with power supply constraints is constructed to control the adjustable load connected to the power grid at a certain time,making the total power load change curve approach the power supply rate curve of the power grid.The experimental results indicate that the algorithm constructed in this study can make the total load power curve infinitely approximate the planned power supply curve;When t=12,the absolute difference between the electricity consumption power obtained from load scheduling and the total load power is maintained between[0,3]kW,while the absolute difference fluctuation range of the real-time distributed adjustable load control algorithm without power supply constraints is between[1,6].From this,it can be concluded that introducing load scheduling with constraints is more effective.
