Abstract
In the context of vigorously promoting the construction of new power systems,aiming at the overvoltage problem of distribution network caused by high proportion photovoltaic access,the existing overvoltage solutions are systematically analyzed and compared,including network parameter adjustment,active power regulation,reactive power regulation and other means,and the way that does not affect the consumption of new energy and is more economical is further adopted.That is,the overvoltage control scheme which combines the price demand response with the PV reactive power control.First,the elastic coefficient of demand response of each user connected to the transformer is obtained.Under the constraints of voltage not exceeding the limit,electricity price within a reasonable range and photovoltaic on-site consumption,the comprehensive reactive voltage optimization model of the distribution network is established to minimize the cost of demand response of the power grid company,and the particle swarm optimization algorithm is used to solve the problem.Finally,the simulation analysis is carried out on the improved IEEE33-node system,and the simulation results show that the reactive voltage integrated control method can be used for photovoltaic absorption on the basis of fully considering the user's demand response elasticity,and the voltage regulation effect is both effective and economical.关键词
