RUNNING MODE DESCRIPTION
PCS + GENSET SYSTEM
PCS supplies power for load in VSG (Virtual Synchronous Genset) mode. When storage loading power is greater than start power of scheduled genset or battery pack SOC is lower than cutoff discharge SOC, genset will start. If genset and storage battery pack share the load, when load power is lower than allowed storage charge power, genset will charge the battery pack with constant voltage and frequency of storage rated charge power. When battery pack SOC is greater than cutoff charge SOC, genset will not charge for battery pack, genset and storage battery pack share the load (NOTE: Converter droop and genset droop should be set as same). When load power is lower than stop power of scheduled genset, genset will stop.
PV + PCS + GENSET SYSTEM
- ECONOMY MODE
If solar energy and storage energy supply power for load, when storage power is greater than start power of scheduled genset or battery pack SOC is lower than cutoff discharge SOC, genset will start. If PV outputs with max power, converter and genset share left load, when load power is lower than PV output power, PV output power is limited, genset reverse power is prevented and storage battery pack overcharge is prohibited. The solar energy takes load first, only supplies power for storage battery pack when solar energy is sufficient. When load power is lower than stop power of scheduled genset and battery pack SOC is greater than cutoff charge SOC, genset will stop.
- POWER MAINTAINING MODE
If solar energy and storage energy supply power for load, when storage power is greater than start power of scheduled genset or battery pack SOC is lower than cutoff discharge SOC, genset will start. If PV outputs with max power, storage converter and genset share load, when load power is lower than storage allowed charge power, genset will charge the storage battery pack with constant voltage and frequency of storage rated charge power; otherwise, when load power is greater than PV power, PV outputs with max power, genset and storage share left load. When load power is lower than PV output power, PV output power is limited, genset reverse power is prevented and storage battery pack overcharge is prohibited. When load power is lower than stop power of scheduled genset and battery pack SOC is greater than cutoff charge SOC, genset will stop.
