Research on the optimization method of multi energy interconnected microgrid configuration and operation based on lifecycle cost

摘要

To solve the problem of the low return on investment in the traditional micro grid, multi energy interconnected micro grid were constituted by distributed photovoltaic, gas turbine, combined cooling heating and power supply system (CCHP). Because power generation of distributed photovoltaic has uncertainty and the load of cold, hot and electricity is unbalance, the optimizesion of microsource configuration and its operation must be made. The method of the genetic algorithms and linear programming is used to solve these. This optimize method was verified by MW-levels comprehensive community which the results show that the multi energy interconnected microgrid has economy and promotion value under the current price system and the condition of Comprehensive community.
