使用化石燃料满足寒冷地区的供暖需求可能会产生过多的温室气体排放问题，因此用可再生能源驱动的电热泵取代传统供暖系统是一个理想的目标。为了帮助解决这一问题，本文探讨了引入独立的微电网，该微电网由天然气联合循环和大型光伏（L-PV）发电源组成，并伴有电热泵容量。这些结果有助于明确L-PV对该微电网总输出的最佳输出速率。在此基础上，从供需平衡误差的角度对co2分体式循环热泵动态特性模型进行了分析。本文表明，引入拟议的微电网可以显着减少环境和经济影响。本研究阐明了在电能质量管理下的寒冷地区微电网的环境能力和经济效益。如果以日本政府官方公布的国内价格为基准，参照拟议微电网的电力单价和二氧化碳排放量，札幌拟议系统的二氧化碳减排量和电力单价预计将分别减少48%和30%。
Fulfilling heating requirements in cold regions using fossil fuels can create problems in terms of excessive greenhouse gas emissions, making the replacement of conventional heating systems with electric heat pumps powered by renewable energy sources a desirable goal. To help address this issue, this paper examines the introduction of independent microgrids consisting of natural gas combined cycle and large-scale photovoltaic (L-PV) generating sources accompanied by electric heat pump capacity. These results help to clarify the optimal output rate of L-PV to the overall output of such a microgrid. Furthermore, this paper examine a dynamic-characteristics model of a CO2split cycle heat pump in terms of the error of the supply-and-demand balance. This paper show that introduction of the proposed microgrid can significantly reduce the environmental and economic impact. This study clarified the environmental capability and economical efficiency of the microgrid for cold regions under management of electric power quality. When an electric power unit price and CO2emissions of the proposal microgrid are referred to the domestic price based on official announcements of the Japanese government, the amount of CO2reduction and electric power unit price of the proposal system can expect 48% and 30% reduction in Sapporo, respectively.
