Dual Semi-Definite Programming Method for Dynamic Optimal Power Flow With Energy Storage Device
摘要
Abstract
Dynamic optimal power flow (DOPF) in microgrids is an optimal power flow problem considering couplings among 24 time intervals in a whole day, consisting of ramp rate constraints of conventional generating units and energy balance constraints of distributed storage devices. Interior-point method with the second order convergence can be used to solve the problem quickly, but it cannot guarantee global optimum solution. This paper applies dual semi-definite programming (DSDP) method to solve this problem. Original DOPF model of a isolated microgrid and its transformation to DSDP model are presented in detail. The paper gives a strict global optimality criterion. Meanwhile, strong nonlinear model of energy storage device is transformed into a linear model and corresponding proof is given. Test results on a real microgrid and IEEE 30-bus system show that DSDP can solve this DOPF problem efficiently and find global optimum solution.关键词
