Abstract

The invention provides a sea island microgrid control system and control method. The sea island microgrid control system comprises an energy storage subsystem, a photovoltaic subsystem, a wind power subsystem, a controller, a diesel generator, a first power distribution cabinet, a second power distribution cabinet and a load, and is characterized in that an energy storage converter in the energy storage subsystem is connected with a battery management system, the battery management system is connected with a battery pack, and both the energy storage converter and the battery management systemare connected with the controller; a photovoltaic array in the photovoltaic subsystem is connected with a photovoltaic inverter; a wind turbine array in the wind power subsystem is connected with a wind turbine inverter; both the photovoltaic inverter and the wind turbine inverter are connected with the controller; the energy storage converter, the photovoltaic inverter and the wind turbine inverter are all connected with the first power distribution cabinet, and both the first power distribution cabinet and the diesel generator are connected with the second power distribution cabinet; and theload is connected with the controller through an electric meter. The sea island microgrid control system can balance wind-solar power generation and energy storage, and provides a continuous and stable power supply for the load on the island.

Description

technical field [0001] The application belongs to the technical field of energy storage control, and in particular relates to a method for controlling an energy storage subsystem of an island microgrid. Background technique [0002] There are a large number of islands in my country, and there are 6,536 islands with an area of ​​more than 500 square meters. The traditional island power supply is provided by diesel generators. In recent years, the power generation of diesel generators has become more and more difficult to meet the needs of users, and the cost of long-term diesel transportation and consumption is also very high. In addition, due to the depletion of primary energy and the deterioration of the human living environment, all countries in the world regard the development of new renewable energy as the direction of energy development. Solar energy and wind energy are inexhaustible renewable energy sources. In recent years, the micro-grid industry has developed rapid...
