Abstract

The invention provides a monitoring method for a battery energy storage system with the reactive power regulation function. The monitoring method comprises the steps that 1, a renewable energy power generation equipment monitoring module obtains running data of renewable energy power generation equipment in real time and stores the data; 2, according to the running data of the renewable energy power generation equipment, the output power of the renewable energy power generation equipment within the future preset time is predicted, and the reactive power, capable of being output, of a SVG module is predicted in real time; 3, the SOC of a storage battery module is detected and obtained in real time, and parameters and scheduling information of a power distribution network are obtained in real time; 4, optimal control over the battery energy storage system is achieved with active demands and reactive demands in scheduling information of the power distribution network, the current storage battery energy storage SOC, the future renewable energy power generation equipment output power and the reactive power, capable of being output, of the SVG module as constraint conditions.

Description

Technical field [0001] The invention relates to a monitoring method of a battery energy storage system with a reactive power adjustment function. Background technique [0002] In recent years, under the dual pressure of energy demand and environmental protection, distributed power generation technology represented by photovoltaic, wind power and gas power generation has developed rapidly. Moreover, the emerging concept of microgrid has also been proposed along with the widespread use of distributed energy. However, due to the natural discontinuity of distributed energy sources, the stability of the system is gradually being threatened. In order to give full play to the advantages and benefits of renewable energy power generation, balance its random fluctuations, maintain system stability, improve power quality, and provide uninterrupted Power supply functions, etc., must be equipped with a certain capacity energy storage unit in the system at the same time. [0003] In the...
