Microgrids systems are composed of intermittent energy (e.g. photovoltaics and wind generation) and controllable energy (e.g. fuel-cell cogeneration system and gas engine cogeneration system). The microgrids can not make best use of the high combined efficiency of cogeneration system if the heat-to-power ratio through cogeneration system is different from the heat-to-power ratio from the demand side. So, we installed heat pump water heater in microgrids to adjust the heat-to-power ratio from the demand side. We used a simulation to determine the reduction of CO_2 emissions with microgrids. We observed that microgrids have the optimal composition proportion of cogeneration system and heat pump water heater.
