National grid demand spike caused by unpredictable external factors such as weather heat wave and aged transmission networks has increased over the recent years. The condition is expected to persist given the general outlook of increased energy usage growth and climate change. Traditional static compensation installations are no longer capable of addressing these issues. This has raised the need for ESS solution with dynamic active load support and high energy reserve capacity. The ESS power functions can be fully customized by the ESS EMS and SCADA integration exercise. Some of the popular power functions are voltage sag support, grid frequency correction and load dispatch management.
Mun Hean Large Capacity ESS are fully customized solutions that provide national grid operators, independent power producers and private industrial networks operator an integrated system with turn-key design & built service. Grid networks SCADA command management is supported with IEC 61850 protocol allowing multiple systems of ESS to be remotely managed from the operator’s Load Dispatch Center. High availability ESS control configuration with full redundancy EMS, BMS controller servers are part of the design baseline.
The battery system, PCS, EMS/BMS controller, fire hazard control and water-cooled designed system ensure are designed into 20feet or 40feet IP54 functional container unit. The battery system for Large Capacity ESS is designed for a 20years lifespan. Different battery chemistry is available to best suit the energy delivery profile such as short-duration / high peak power and long-duration / flat baseload support. Battery system capacity of up to 5MWh @40feet container is available.
All Large Capacity ESS system comes with professional engineering endorsement and design compliance to local national grid code regulation for power grid installation standards. Specific type tests on all system components can be prepared. Longterm engineering support service and comprehensive maintenance are offered as package for Large Capacity ESS system projects.
