The transient model of the multi-unit pumped storage system can be developed by coupling the hydraulic system and the pump turbine system. Therefore, the dynamic model of the multi-unit pumped storage system as shown in Eq. (23) can be obtained by combining Eqs. (17), (22).
To this end, a multi-timescale nested energy storage capacity optimization model for multi-energy supplemental renewable energy system with pumped storage hydro plant based on a three-battery group control operation strategy is proposed.
The procedures to simulate the operation were as follows: Step 1: According to the water diversion rule, the amount of diverted water was defined as a function of the current storage of the recipient reservoir and maximum amount of diverted water, as described by Eq. (1).
A two-tier energy storage capacity optimization allocation model nested in multiple time scales is established. The model mainly utilizes the advantages of power regulation speed and capacity differentiation between hydropower and BESS, and fully exploits the ability of hydropower to flexibly regulate fluctuations.
In this paper, considering the coupling effect of the hydraulic system, a nonlinear dynamic model of the multi-unit pumped storage system is established by combining the hydraulic system and the pump turbine system. The reliability of the proposed model is proved in the process of the two-unit rejecting full load at the same time.
The multi-unit pumped storage system includes a common penstock, pipes, servo systems and generators of each subsystem. To development the dynamic model of the multi-unit pumped storage system, its frame diagram is presented in Fig. 4. Fig. 4. Frame diagram of the multi-unit pumped storage system.
