Chance-Constrained Operation Strategy for CCHP Microgrid Wei Shangshang, Li Yiguo, Zhang Junli, Wu Xiao

Abstract

Operation strategy is critical to the economic performance of combining cooling, heat and power (CCHP) microgrid. This work took different costs of operation, maintenance, startup and shut down, storage aging, and different nonlinear characteristics of tariff electricity, storage loss and COP, etc. into consideration. To tackle the uncertainties of renewable energy and load demands, a chance-constrained operation strategy was established. PSO algorithm was applied to solve the problem. Simulation results show that uncertainty of CCHP deteriorates system economic performance compared with deterministic economic operation strategy. And following electrical load and following thermal load are inefficient for economic operation of CCHP microgrid.
