The method comprises the following steps: S1, a wind power generation equipment and photovoltaic power generation equipment monitoring module acquires operation data of wind power generation equipment and photovoltaic power generation equipment in real time and stores the data; S2, according to the operation data of the wind power generation equipment and the photovoltaic power generation equipment, output power of the wind power generation equipment and the photovoltaic power generation equipment in future preset time is forecast; S3, an SOC of a storage battery module is detected and acquired in real time, and a power demand condition of loads in the micro-grid is acquired in real time; S4, parameters and scheduling information of a large-scale power grid are acquired in real time and a power demand of a connection point of the micro-grid and the large-scale power grid in future time is forecast; S5, by using a power demand of a connection point of an energy storage power station and the large-scale power grid, a current SOC of energy storage of a storage battery, a current power demand of the loads in the micro-grid and future output power of the wind power generation equipment and the photovoltaic power generation equipment as constraint conditions, optimized operation of the micro-grid is realized.

Description

Technical field [0001] The invention relates to an operation and monitoring method of a microgrid with an energy storage system capable of suppressing power fluctuations. Background technique [0002] Micro-Grid is also translated as micro-grid. It is a new type of network structure. It is a system unit composed of a group of micro power sources, loads, energy storage systems and control devices. It is an autonomous system that can realize self-control, protection and management. , It can be connected to the external power grid or run in isolation. [0003] As a supplement to the ultra-high voltage, long-distance, and large-scale grid power supply mode, the micro-grid based on wind power and photovoltaic power generation represents the new development direction of the power system. Wind energy and solar energy are clean and renewable energy sources, but there are problems of randomness and volatility, which have a series of impacts on the grid. The degree of power volatility dire...
