Abstract

The invention relates to a power prediction based monitoring device for a battery energy storage power station. The monitoring device comprises a photovoltaic power generation equipment monitoring module for monitoring photovoltaic power generation equipment in real time and predicting the power generation power of the photovoltaic power generation equipment; a storage battery monitoring module for monitoring an SOC (System on chip) of a storage battery module in real time; a large power grid connection module for acquiring the operating condition of a large power grid and the related scheduling information from a large power grid regulation center in real time; an SVG (dynamic reactive power compensation equipment) monitoring module for monitoring an SVG module in real time and controlling the reactive output of the SVG; a grid-connected operation monitoring module for controlling connection with an energy storage system or isolating the large power grid; a load monitoring module for monitoring the load in the energy storage power station in real time; a center control module for determining the operation strategy of the energy storage system and sending a command to all modules in the monitoring device and executing the operation strategy; and a bus module used for communication connection of all modules of the monitoring device.

Description

Technical field [0001] The invention relates to a monitoring device of a battery energy storage power station based on power prediction. Background technique [0002] As a supplement to the power supply mode of ultra-high voltage, long-distance, and large power grids, microgrids represent a new development direction for power systems. When a microgrid containing distributed energy sources is operated in parallel with a large power grid, the internal load of the microgrid is jointly provided by the distributed energy sources in the microgrid and the large power grid. When the distributed energy output is greater than the load in the microgrid, the microgrid sends power to the large grid, and when the distributed energy output is less than the load within the microgrid, the microgrid absorbs power from the large grid. Due to the volatility of the load, and the inherent intermittency and volatility of distributed energy, the power fluctuation range at the public connection point of...
