In recent years, photovoltaic power generation technology has advanced rapidly, and the installed capacity has increased rapidly. However, photovoltaic power generation has shortcomings such as intermittent and uncontrollable. Before processing, large-scale direct access to the power grid will bring great impact and affect the stable operation of the power grid. Adding the energy storage can make the photovoltaic power generation smoothly and stably output to the power grid, and the large-scale access to the power grid will not affect the stability of the power grid. And photovoltaic + energy storage, the system has a wider range of applications.
Working principle
When the photovoltaic system is running, the battery is charged by the MPPT controller; when there are loads working, the battery will release electricity, and the magnitude of the current is determined by the load. The energy storage system is connected to the grid, and if the load is small and the battery is fully charged, the photovoltaic system can supply power to the grid. When the load power is greater than the photovoltaic power, the grid and photovoltaic can supply power to the load at the same time. Because the photovoltaic power generation and load power consumption are not stable, it is necessary to rely on the battery to balance the system energy.
