The construction and safety of energy storage power stations are important issues in the energy field. With the popularity of renewable energy and the demand for power systems, the demand for energy storage power stations for enterprises is also increasing. The following will discuss issues related to the construction and safety of industrial and commercial energy storage power stations.
Construction of industrial and commercial energy storage power stations
- Site selection
The site selection of an energy storage power station is a key step in the early stages of construction. The location selection of a power station needs to consider factors such as geographical location, geological conditions, climate, etc., as well as the needs of the power system and future expansion possibilities. Design aspects need to consider the type, battery capacity and layout of energy storage equipment, as well as the design of the power system and the design of the control system. The general principles are:
1) Try to choose a place away from offices and dense crowds, close to the access point power distribution room (within 100m recommended) and convenient for cable routing;
2) Choose a hardened site that is easy to transport, hoist, and load-bearing.
- Selection of energy storage equipment
The selection of energy storage equipment is undoubtedly a crucial link in the construction process of energy storage power stations. This link is not only related to the operational efficiency of the entire power station, but also directly related to the safety and stability of the power station. In the current market, there are two main mainstream energy storage technology routes: centralized energy storage and distributed energy storage. Each of these two technical routes has its own advantages and disadvantages. Therefore, we need to make careful choices based on different actual needs.
The advantage of centralized energy storage is its large scale and low unit cost of energy storage. This energy storage method is conducive to the large-scale application of electric energy, thereby reducing operating costs. However, centralized energy storage also has some disadvantages, such as long construction period, large floor area, imprecise control, and certain safety hazards.
Distributed energy storage has greater flexibility, faster response, and can achieve refined management, thereby improving energy storage utilization efficiency. It is suitable for industrial and commercial scenarios with short construction periods and limited spatial locations.
