Delta has announced the integration of its lithium-ion energy storage system into Mitsubishi Heavy Industries Engine and Turbocharger's innovative triple hybrid stand-alone power supply demonstrated in the Triple Hybrid Station, a demo power plant located in MHIET´s manufacturing site in Sagamihara, Kanagawa Prefecture, Japan.
"The Triple Hybrid stand-alone power supply system combines renewable energy such as solar power with a reciprocating engine generator and an energy storage battery system, to allow for optimal power stabilisation control. The system's main advantage is its ability to stabilise the volatile output of renewable energy by combining three types of power sources, ultimately enabling low-cost power supply provided by an environmentally-friendly, multi-purpose distributed generation system," said MHIET.
The lithium-ion battery system integrated by Delta into MHIET´s system boasts a superior 4C charging and discharging power rate to rapidly smoothen sudden fluctuations from the solar power generation due to diverse weather conditions.Thus, Delta´s energy storage solution enables stable power supply according to power demand in combination with the reciprocating engine. Delta is developing next-generation applications, such as VPP (Virtual Power Plant), self-consumption and grid stabilisation by utilising its lithium-ion battery system and renewable energy technologies to accelerate the decarbonisation of our future.
The MHIET triple hybrid demonstration power plant uses Delta´s 331kWh-container-type battery energy storage solution, four 125 kW power conditioning systems, and four 50 kW PV inverters with conversion efficiency up to 98.6%. Other key features of the offering include:
