1微能源网及其政策背景进入21世纪后,集成了风光气等多种能源输入、冷热电等多种产品输出的多能互补微能源网逐步得到了发展,由于其充分利用可再生能源以及能源的梯级利用技术进行冷热电一体化生产、计划和调度,能够显著提高综合能源利用率、减少二氧化碳排放,并能帮助用户选择更经济的能源。随着燃气价格的下调,目前分布式燃机的发电成本仅为0.55元/(kW·h)左右(随各地燃气价格不同而异),而且分布式光伏和风电的边际成本几乎为零,因此即便考虑初期建设费用,微能源网面对工商业
1 Micro Energy Network and Its Policy Background After entering the 21st century, multi-energy complementary micro-energy nets integrated with a variety of energy input such as Fengguang gas, and output of various products such as cold and heat electricity have been gradually developed. Due to their full use of renewable energy As well as energy-based cascading technologies for integrated production, planning and dispatch of cogeneration can significantly improve overall energy efficiency, reduce carbon dioxide emissions and help users to choose more economical energy sources. With the gas price cut, the current generation cost of distributed gas turbines is only about 0.55 yuan / kWh, which varies from gas price to gas price, and the marginal cost of distributed PV and wind power is almost zero. Even considering the initial construction costs, micro-energy network to business
