Abstract: This paper established a kind of microgrid model of combined cooling heating and power (CCHP) based on fuel cell. With the minimum cost of system operation as the goal, this paper adopted the particle swam algorithm based on Monte-Carlo analog to carry out study and analysis of the optimization operation characteristics of the system under different load modes and different electricity price mechanism. Actual example analysis shows that the study project can provide reasonable suggestions for micro source optimization allocation, operation management and present economic dispatch etc aspects of CCHP type of microgrid under different working conditions.
Key words: fuel cell; microgrid; combined cooling heating and power; operating optimization
