EMS Scada Systems for Energy Storage Projects

SCADA Solutions Customized for Energy Storage Projects

Our SCADA systems are purpose-built to support the full scope of energy storage project requirements. At the heart of these systems is the Energy Management System (EMS), which functions as an intelligent supervisory platform that manages the dispatch of one or more energy storage or power generation units. The EMS ensures real-time monitoring and optimal performance of each system, while also enabling smooth integration and operation of multiple assets.

The EMS is designed to tackle two major technical challenges commonly encountered in large-scale energy storage management:

    • Efficient scheduling of energy storage systems to ensure secure operation and achieve maximum performance benefits.
    • Harmonization of diverse systems, including those of varying capacities and technologies. Since many storage solutions incorporate components from different manufacturers, the EMS plays a key role in ensuring they work together seamlessly.

EMS SCADA HMI Graphical Interface Features:

    • Accessible via web browser
    • Fully customizable to meet project-specific needs
    • Supports modifications to control settings and operational modes
    • Displays Point of Interconnection (POI) data, including MW, MVar, voltages, and currents
    • Provides detailed inverter metrics such as MW, MVar, voltages, and currents
    • Monitors battery system status, including state of charge (SOC), state of health (SOH), power output (MW), voltage, and current
    • Offers battery module-level visibility, including SOC, SOH, temperature, current, and voltage
    • Functions as the Master Site Controller for real and reactive power dispatch, ensuring compliance with LGIA and PPA requirements
    • Includes comprehensive alarm and event monitoring

Arkans EMS Solution is custom built to facilitate:

    • ITC compliance: Avoid charging from Grid:
    • Log all charging activity to establish 75-100% charging from renewable energy source in first five service years to fully capture the tax credits.
    • Control export of PV Power to Grid per user specific maximum limit by charging ESS.
    • Application to capture solar energy that is otherwise wasted during:
    • Mid-day inverter clipping
    • Curtailment from the utility.
    • ESS discharge to meet export requirements without exceeding export requirements.
    • Scheduled P/Q control of ESS at any time.
    • Any additional site-specific requirements.
