Abstract
With the intensification of the global energy crisis and the enhancement of environmental protection awareness, smart microgrid has been widely concerned as a small power system that can efficiently integrate distributed renewable energy and achieve supply and demand balance. As one of its core technologies, the energy management strategy of smart microgrid is of great significance to ensure the safe and stable operation of microgrid, improve energy utilization efficiency and promote the wide application of renewable energy. This paper focuses on the energy management strategy of smart microgrid, firstly analyzes the background and challenges of the current development of smart microgrid. With the wide application of renewable energy, microgrid is faced with challenges such as intermittency of energy supply and uncertainty of user demand. How to effectively manage these resources, achieve supply and demand balance and optimize allocation has become an urgent problem to be solved. This paper discusses the main content and key technology of energy management strategy of smart microgrid. Energy management strategy includes energy scheduling, energy storage management, demand side response and other aspects, aiming to achieve efficient energy utilization and supply and demand balance in microgrid through reasonable scheduling and control means. Among them, energy storage system is an important part of microgrid, and its charge and discharge strategy plays an important role in balancing supply and demand relationship and improving system stability. At the same time, as an important means to realize the interaction between users and the power grid, demand side response can adjust the user load to respond to the power grid demand, which helps to alleviate the power grid pressure and improve the energy utilization efficiency. In the research method, this paper uses mathematical modeling, optimization algorithm and simulation analysis and other means. By constructing the mathematical model of microgrid and combining optimization algorithms such as particle swarm optimization algorithm and genetic algorithm, the energy management strategy is optimized. At the same time, simulation analysis verifies the effectiveness and feasibility of the strategy, and provides scientific basis for practical application. This paper summarizes the research results and application prospects of energy management strategies for smart microgrids. The results show that reasonable energy management strategy can significantly improve the energy utilization efficiency of microgrid, reduce the operating cost and improve the system stability. In the future, with the continuous development of smart grid and energy Internet, the energy management strategy of smart microgrid will be further improved and optimized to make greater contributions to the realization of sustainable development goals.
