In face of the randomness and volatility of the renewable energy generation and the uncertainty of the load power consumption in the new power system, the optimal configuration of energy storage is very important, so that it can effectively act as a flexible power source or load when the system fluctuates.
To ensure the efficient management of hybrid energy storage, reduce resource waste and environmental pollution caused by decision-making errors, systematic configuration optimization model as well as value measurement of hybrid energy storage in the new power system are deeply studied in this paper.
in energy need to be balanced. One of the main functions of energy storage, to match the supply and demand of energy (called time shifting), is essential for large and small-scale applications. In the following, we show two cases classifi ed by their size: kWh class and MWh class.
The IEC recommends industry to develop storage management systems which will allow use of a single storage system for not just one but many of the applications described in the IEC study. Controllers and management systems are required which function independently of the types of the batteries being controlled 11.
Herein, in the face of the complex and diverse flexibility regulation demands from the new power system, the application of the hybrid energy storage system (HESS) not only helps to improve the efficiency of flexibility regulation, but also can expand the auxiliary service functions and improve the overall flexibility of the new power system .
Batteries and the BMS are replaced by the “Energy Storage Medium”, to represent any storage technologies including the necessary energy conversion subsystem. The control hierarchy can be further generalized to include other storage systems or devices connected to the grid, illustrated in Figure 3-19.
