Managing Distributed Energy Resources

ACS has developed economical Distributed Energy Resources Management Systems (DERMS) that flexibly integrate with existing SCADA systems, feeder devices, communications systems and remote terminal units.

DERMS is a broadly used term that describes a system that a utility can implement to maximize the use of Distributed Energy Resources both economically and efficiently.

PRISM
  • Renewable Generations such as wind and solar
  • Conventional generation such as diesel and gas generators
  • Energy Storage Systems
  • Energy programs including industrial, commercial, and residential consumers for both market and demand response
  • A combination or aggregation of the above resembling an island or microgrid

  • Timely Development

    The development of a DERMS has been a logical progression of the distribution control and automation systems ACS has been delivering for over 40 years.

  • Advanced Control

    The advanced control of transformer load tap changers, substation and feeder capacitor banks, feeder breakers, voltage regulators, and feeder sectionalizing devices needed to optimize the performance of DERs is available within the PRISM platform.

  • Seamless Integration

    Our solutions are designed to integrate seamlessly into legacy systems and existing equipment.

  • Advanced Automation

    Our DERMS is an advanced application of existing automation systems such as voltage regulation and optimization (VVO) as well as automated fault location isolation and service restoration (FLISR) with a combined goal of maximizing the injection of renewables in a multitude of scenarios that includes the use of energy storage systems.

  • Extending Our Reach

    Advancements in communications are allowing us to extend our reach and collect large amounts of meaningful data from a variety of devices, including DERs, to further optimize grid performance as well as contribute to additional reliability, and resiliency.

  • Flexible Location

    A DERMS can be applied at a centralized location typical to legacy utility management systems, distributed closer to the resources who’s operation needs to be coordinated, or a combination of both. The choice is dependent on the utility’s approach, infrastructure, and needs at the time, which can vary widely.

A recent 2017 study has concluded that there are advantages to applying an advanced level of automation at the substation level to optimize a system while still reporting critical information back to central operations.

Some of these advantages include speed and resiliency. Localized intelligence alleviates latency concerns that may be encountered with centralized control, especially during widespread outage conditions related to extreme weather or other service interruptions. Distributed intelligence and control allows for and island or localized state that can maintain effective operation independent of a central system.

The study findings conclude that the ACS CENTRIX DERMS:

  • Reduced and prevented reverse power flow
  • Flattened voltage profiles
  • Regulated voltage swings due to load fluctuations faster controlled from the substation
  • Reduced the number of operations of assets such as voltage regulators, switched capacitor banks, etc.
  • Reduced power loss
  • Improved power factor
  • Dynamically adjusted protection settings

DERMS works as follows

PRISM DERMS issues control signals to feeder devices with the objective to optimize the operation of the feeder network. DERMS lowers the end of line Voltage and the line drop Voltage using LTC and regulators and reduces feeder losses through improvement of the power factor with capacitor switching. DERMS specific control to optimize the feeder includes dynamic control of the inverter’s real and reactive power injection from renewables such as photoVoltaic (PV) distributed energy resources and energy storage.
