Three-phase Unbalanced Reactive Power Optimization for Distribution Systems with a Large Number of Single Phase Solar Generators
摘要
Abstract
The extensive penetration of open‐phase running distributed generators ( DGs) such as photovoltaic generators to distribution systems may lead to a serious three‐phase unbalanced condition , which is an intrinsic characteristic of distribution systems . The effect of the traditional reactive power optimization method is poor without considering the unbalanced problem . A three‐phase unbalanced reactive power optimization model for active distribution networks is presented . The model with the objective of minimizing both the negative sequence system voltages and network losses considers continuous and discrete variables e .g . the under‐load tap changers , capacitors banks and static var compensator . The reactive power optimization problem is formulated in rectangular coordinates as a mixed‐integer quadratic programming with the quadratic constraint problem . It is solved by the branch‐and‐bound method and the original problem is divided into a lot of sub‐problems without discrete variables , which are solved to get the control strategy of devices . The simulation results of the modified IEEE 33‐bus three‐phase test system show that the proposed model and method are effective .关键词
