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. From the perspective of demand, energy storage can be applied to very diverse and complex scenarios. The scene can be divided into power generation (renewable energy grid, reducing the abandoned light and abandon wind), power grid side (power peak adjustment, frequency adjustment), user side ( Family, industrial and commercial users), transmission side, and auxiliary services (5G base station spare power supply) and so on. Between the throughput of electricity, not only can it alleviate the abandoned wind and light of the new energy power generation side, but also provides a peak -regulating frequency and frequency -regulating service for traditional thermal power crews, while stabilizing the grid and reducing the volatility of the power grid. User's side demand tends to be diverse. In addition to being favored by portable energy storage, in some industrial and commercial parks, photovoltaic+energy storage/independent energy storage can also help industrial and commercial enterprises charging and discharging at the peak of power at the peak of power. Use electricity price Peak Valley to cash. 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 price of energy storage system manufacturers. Today, Haileienergy will give you an example to introduce the price of energy storage systems.
