Electronic Switching System makes hybrid energy power station possible
Adding an ESS gives you many design options. Like a genset, it can provide spinning reserve functionality to ensure uptime, and it can be configured to ensure optimal genset load. You can use energy source or power source control, and the ESS can run in grid-forming, grid-following, or droop mode (acting as a virtual synchronous generator). You can base charging/discharging on schedular command timers and set up the ESS to communicate with a BCU, BMS, or PCS over Modbus.
