Title    Research on Optimal Energy Scheduling and  Algorithm for Micro grids                       
Abstract
With the increasing fossil energy depletion, environmental pollution and increasing security and reliability requirements for grids, many attentions are paid to distributed generation. We often combine distributed energy resources, load and energy storage units to form a micro grid , in which way we can solve the problem of the uncontrollable distributed generations when they are interconnected with grid.
Economic operation is one of the important factors whether Micro grids can participate in marketing competition. Based on a micro grid model which includes photo-voltaic power generation, wind power, fuel cells, micro turbines and batteries, a dynamic programming method has been used to solve these models for minimum operating cost , best environmental benefits and maximum comprehensive benefits in this paper. A multi-objective energy optimization scheduling model is established to find out how optimal objectives, operation modes of Micro grids, marketing polices, the competitiveness of renewable resources, and heat load affect the energy optimal scheduling results. By mean of the analysis of several examples, the validity of the model and algorithm has been tested.
