Title    Study on The Joint Dispatch and Optimization of Mixed Energy of Heat and Power in Smart Grid Park 

Abstract With the energy shortage and environmental pollution becoming increasingly serious, improving energy structure and energy utilization efficiency and extending solar energy,wind energy and other cleaner energy have become a problem to be solved urgently for researchers all over the world, so the combined heat and power(CHP) system has been widespread concerned because of its energy saving capability,environment friendliness and economic benefit。 CHP system using gas as fuel is based on energy cascade utilization, and can meet the user's demand for heating and power at the same time。

On the basis of CHP system,the paper studies on optimal scheduling of mixed energy of heat and power in the Smart Grid Park combined photo-voltaic power generation。 First, the main power supply equipment and auxiliary equipment have been modeled mathematically。 Secondly, the paper determines the single objective optimization function based on economical efficiency and the multi-objective optimization function based on both economical and environmental efficiency, lists the constraints according to the load balance and equipment’s operating characteristics, establishes optimization scheduling model, and uses linear programming to solute the optimization problem。 Finally, this paper proposes scheduling strategy for a typical day using the analysis of an industrial park in Smart Grid。
