Abstract: The research project on the innovation and practice of green power cluster regulation of "water and light integration" in mountainous distribution networks focuses on the goal of carbon peak attainment and carbon neutrality, implements the important mandate of General Secretary Xi Jinping on "development of electricity", takes the implementation of the strategic objectives of State Grid Corporation as the lead, and based on the characteristics of mountainous distribution networks Based on the characteristics of "abundant water and light resources and weak network structure", the company explores the green energy potential of hydropower and photovoltaic, builds a "three, four, five, three" system (three joint mechanisms, four core technologies, five service models, three safeguards), and completes a distribution network with The system is characterized by "highly transparent distribution network", "water and light integration and complementarity", "green power cluster regulation" and "self-healing recovery from disasters". The project has effectively solved the problems of inadequate perception of the evolution of active distribution network characteristics, inadequate coordination of stock and incremental resources, and inadequate penetration of regulation and operation management, led the high-quality development of green power under the new situation, and formed a win-win "power supply + service" green power ecosystem for the government, power supply companies and enterprises.
