Reactive compensation method for intelligent energy accumulation power generating system

Abstract

The invention discloses a reactive power compensation method of an intelligent energy storage and power generation system. The method can monitor the power generation device, load unit, energy storage device and SVG equipment in real time for the power fluctuation value of the energy storage and power generation system, and thereby Dynamically adjust the power of the energy storage device for the information source, so as to achieve smooth grid-connected power; it can realize the economical operation of the energy storage power generation system, and suppress voltage fluctuations. By collecting data from the energy storage power generation system, a network architecture model is established. Under the power control strategy, the power factor of the power generation device is guaranteed to be constant, and the economic operation is completed through reactive power regulation.

Description

Technical field [0001] The invention relates to a reactive power compensation method of an intelligent energy storage power generation system. Background technique [0002] With the growth of the earth's population and the advancement of the industrialization process in developing countries, all kinds of fossil energy are rapidly exhausted, and the air pollution and ecological environment crisis caused by the use of fossil energy are becoming more and more serious. In order to reduce air pollution, protect the ecological environment, ensure long-term stable supply of energy, gradually change the existing energy structure, and vigorously develop green energy has become the consensus of all countries. [0003] With the maturity of wind power generation, photovoltaic power generation, wave power generation and other renewable energy power generation technologies, more and more renewable energy storage power generation systems are connected to the power grid in a distributed man...

Problems solved by technology

However, the existing technology only monitors the power generation unit and load unit in the microgrid, does not effectively monitor the energy storage system, and cannot timely adjust the working status of the battery in the energy storage system, which may easily cause the grid connection point between the microgrid and the external grid. The power fluctuates greatly, and the unstable power supply has a negative impact on the safety and reliability of power distribution
