Aiming at the characteristics of volatility and intermittence of distributed generator and load in microgrid, this paper presents a dynamic economic dispatch model involving confidence level of economy and reliability risk by using chance constraint. The economy of new model considers both generation cost of controllable units and over- and underestimate risk cost due to uncertainty in microgrid. For overestimate risk cost, three kinds of priority strategies of power adjustment are adopted. One is to purchase the power from the major network. The second is based on the controllable generating ...
