技术领域technical field
本实用新型涉及一种微网系统，尤其是涉及一种智能化微网系统。The utility model relates to a micro-grid system, in particular to an intelligent micro-grid system.
背景技术Background technique
目前，以能源多元化、清洁化为方向，以优化能源结构、推进能源战略转型为目标，以清洁能源和智能电网为特征的新一轮能源变革正在全球范围推进。面对新形势，国家电网公司提出加快建设特高压电网为骨干网架，以信息化、自动化、互动化为特征的坚强智能电网，积极促进清洁能源发展，为实现社会、经济又好又快地发展提供强大支撑。At present, with the direction of energy diversification and cleanliness, the goal of optimizing energy structure and promoting energy strategic transformation, a new round of energy transformation characterized by clean energy and smart grid is advancing globally. In the face of the new situation, the State Grid Corporation proposed to accelerate the construction of UHV grid as the backbone grid, a strong smart grid characterized by informatization, automation, and interaction, and actively promote the development of clean energy, in order to achieve sound and rapid social and economic development. Development provides strong support.
微型电网(微网)由于采用了大量的绿色清洁的分布式能源且能为用户提供可靠的、高质量的电能而成为今后电网发展的重要组成部分。现有微网系统是由燃气轮机或柴油机为原动力，但随着能源危机的出现，导致石化能源的不断长价，其微网的电价也随之上升；由再生能源组成的微网是今后发展的方向。然而，由于再生能源的正常使用受到天气、气候能诸多条件制约，只由再生能源组成的微网系统仍不能完全满足受控端负荷的使用需求，所以要为微网系统配备储备能源。Microgrid (microgrid) has become an important part of the future grid development because it uses a large number of green and clean distributed energy sources and can provide users with reliable and high-quality electric energy. The existing micro-grid system is driven by gas turbine or diesel engine, but with the emergence of the energy crisis, the price of petrochemical energy continues to increase, and the electricity price of the micro-grid also rises; the micro-grid composed of renewable energy will be developed in the future direction. However, since the normal use of renewable energy is restricted by weather and climate conditions, the microgrid system composed only of renewable energy cannot fully meet the demand of the controlled end load, so it is necessary to equip the microgrid system with reserve energy.
