GPM Hybrid Energy Management System (HEMS)
Control system to optimize operations, ensure grid code compliance, and efficiently control PV solar and BESS technologies at your power plant.
GPM’s Hybrid Energy Management System (HEMS)
Ensure optimal operation, maintain grid code compliance, and efficiently coordinate and control both PV solar and BESS technologies through our Hybrid Energy Management System (HEMS). GPM’s Hybrid Energy Management System consists of several integrated GPM software services designed to manage the complexity of hybrid power plants. Operate during peak demand periods and grid disturbances, independent of weather conditions and time of day, as long as energy is available in the Battery Energy Storage System (BESS).
Ensures optimal operation and seamless grid code compliance
Performs accurate active and reactive power control
Maintains flexible operations during peak demands and grid disturbances
Balances the State of Charge (SoC)
Automates site control through system integrations
Creates a production schedule based on generation forecasts
GPM HEMS: grid code compliance
GPM’s Hybrid Energy Management System (HEMS) ensures grid-friendly control for PV solar +BESS hybrid plants, offering customizable real-time control and seamless integration with GPM SCADA and GPM PPC systems as well as third-party systems.
GPM’s HEMS for solar pv and battery storage not only oversees the hybrid site’s operations by coordinating various generation technologies and ensuring grid compliance, but it also provides advanced features to efficiently manage and safeguard the BESS system.
GPM HEMS: power management system
Once GPM’s PPC sets the active power point at the Point of Interconnection (POI), HEMS distributes the setpoint between BESS and PV inverters, allowing operators to choose between modes including BESS Priority Control, and PV-BESS Coordinated Control for flexible power management.
BESS-PV coordinated control
BESS-PV coordinated control manages both the PV plant and the BESS to follow the active power setpoint at the POI, while prioritizing the maximum available PV generation.
BESS priority control
Four different control modes are available: PV plants can adjust their power output to meet POI active power setpoints, or local setpoints can be satisfied independently of POI setpoints.
FFR mode
The system maintains the PPC’s setpoint at POI through PV generation, with the BESS triggering only when a frequency event occurs, regulating plant output power accordingly.
Irradiance ramp mode
The BESS in Irradiance Ramp Control compensates for sudden power fluctuations at the PV plant caused by solar irradiance changes, ensuring a fixed maximum active power ramp rate at the POI. When fluctuations are below the set rate, the BESS stays in standby mode.
BMS
GPM’s standard BMS ensures proper maintenance and longevity while improving operational efficiency and flexibility. The BMS independently modifies active power commands for various functions and balances the SoC at the Power Conversion System (PCS) level. Control options include: Automatic Mode, Manual Mode, and BESS OFF Mode.
Scheduler, Dispatcher and Optimizer
Optimize the control of the plant by enabling automation of command execution for plant control and ensure the generation of active power commands based on generation forecasts.
Scheduler
Simplifies plant automation by executing predefined commands from a CSV file at scheduled times, ensuring seamless operation. Configures up to 20 commands in advance for efficient control.
Dispatcher
Maximizes efficiency by optimizing renewable energy use and managing BESS storage. Dispatcher adapts to changing conditions based on generation forecasts, and ensures reliable, autonomous plant operations with flexible controls.
Optimizer
Boosts hybrid plant efficiency and profitability by generating active power schedules that reduce energy waste and optimize power flows. With data-driven automation and market price integration, PV generation forecasts, and energy market price predictions it empowers operators to manage stored energy strategically.
