The basic task of energy storage system is to overcome the temporal or local differences between power grid supply and demand, ensure power grid security, energy storage ring in power grid can save energy and effectively regulate power and energy. It is an important prerequisite for realizing intelligent management of power grid and an effective means for rational utilization of renewable energy, and provides a good way to solve the problem of energy shortage. The energy storage converter is the core link to realize the smart grid, and the energy storage system also plays an important role in the microgrid. The energy storage converter can realize the independent operation of new energy photovoltaic power generation, distributed wind power generation and small-scale microgrid system, and can operate independently with the battery system to form a power grid system relatively independent of the power grid. Its important significance is that it can be used as the basic unit of smart grid to establish an independent microgrid in remote areas, To save a lot of auxiliary power distribution investment.
