In the smart grid, the use areas of the energy storage system are divided into three stages: the initial stage is the auxiliary service market, which is used to deploy power quality. It is currently the most common energy storage application. It exists in all aspects of power generation, transmission and distribution and electricity. There will be more energy transfer services at the beginning of the mid -term, which also involves the energy regulation generated by the import of renewable energy and the adjustment of the power of the peak. In the later stage, it is a smart grid system that focuses on local independent power generation and power storage. The addition of energy storage can make new energy a high -quality power supply of power grids, while helping new energy to achieve multiple values, including meeting the hard requirements of the grid, smooth contribution curve, and auxiliary services. We calculate the three scenarios of a photovoltaic ground power station configured with energy storage: respectively: no energy storage, energy storage (only reducing power abandonment function), and energy storage (reducing power abandonment at the same time). When the energy storage system only has the function of peak -cutting, it is difficult to meet the requirements of 8%, because the additional income obtained by electricity abandonment is not enough to offset energy storage costs. However, after the energy storage is involved in the frequency adjustment market, it can get additional auxiliary service revenue. Although the internal yield is still lower than the non -energy -storage scenario, it is already higher than 8%. However, as energy storage costs have further reduced or the revenue of assistance services is increased, economics is also expected to be resolved. Some customers consult the quotation of the smart grid energy storage system. Today, Haileienergy will give you an example to introduce the quotation of the smart grid energy storage system.
