Abstract
Renewable energy and energy storage combined system cannot only realize load transfer, load shifting, energy saving and emission reduction, but also ensure the stability and safety of power grid. Economic dispatch of energy storage system under micro-grid environment is a typical multi-stage stochastic programming problem. The purpose of this paper is to propose an economic dispatch model for the energy storage system satisfying the non-anticipative constraints. The objective function is constructed based on the minimum dispatching cost of the micro-grid, and the accurate mathematical description of the feasible region is given. By solving these problems, we can obtain economic dispatch results of the energy storage system satisfying the non-anticipative constraints. The proposed methods are tested on four different cases, and the results suggest the methods are effective.
