Solar power energy storage systems are designed according to four systems:
- Photovoltaic power generation systems;
- Energy storage systems;
- Intelligent power distribution systems
- Energy management systems.
The energy storage system is composed of lithium-ion phosphate battery and energy storage converter PCS. It needs to be based on the total load power and load working characteristics of users. In order to facilitate transportation and installation and reduce the floor space, the energy storage system design of the project is based on lithium iron phosphate battery energy storage technology, which the actual power consumption and energy storage system, as well as the comprehensive efficiency of energy storage system should be considered.
The energy storage system is mainly composed of lithium iron phosphate battery unit, DC BUS unit, battery management system (BMS), energy storage converter (including isolation transformer) (PCS), container body (including power distribution), energy management system (EMS), monitoring system, automatic fire control system and temperature control system. We have broken into sub sections how to build each energy system:
