An Active and Reactive Power Joint Real-time Dispatch Approach for Microgrid Using Model Predictive Control
摘要
Abstract
In microgrid, generators are generally close to the load and the impedance ratio of transmission lines is relatively large. Bus voltage depends on the active power flow as well as the reactive power flow. Also, the reactive power upper limits of power sources are subject to the active power. An active and reactive power joint real-time dispatch approach was proposed with consideration of the bus voltage constraint, by which voltage control in microgrid was achieved in process of real-time economic dispatch. The uncertainties of photovoltaic and wind power generations were represented by scenarios. The model predictive control (MPC) algorithm was used for the receding horizon real-time optimal dispatch and voltage control. Case studies showed that: the proposed active and reactive power joint dispatch approach can always keep the voltage within the permitted range. Compared with the active and reactive power independent dispatch approach, the economic efficiency and voltage quality of the microgrid are both improved by the proposed method.关键词
