并在此基础上分析了不同的分段数对DG运行点可行域覆盖率的影响。

Abstract

In allusion to the situation that the operating points of distributed generator (DG) cannot satisfy the power characteristics in microgrid energy management

a microgrid economic dispatch model which considers the power characteristics of DGs is established. The model

which linearizes PQ capacity limitation of DG based on analytic geometry

is solved. Such that it can effectively take the power characteristics of DG with voltage source inverter

doubly-fed induction generator and synchronous generator into account. In the framework of multi time-scale microgrid economic dispatch

the proposed model is verified on a microgrid system. Meanwhile the effects of different segments on the feasible region coverage of DG operating point are analyzed. This work is supported by National Natural Science Foundation of China (No. 51307063)

and Specialized Research Fund for the Doctoral Program of Higher Education (SRFDP) of China (No. 20120172120042).
