A Distributed Energy Resource Management System (DERMS) is a software solution for controlling and coordinating a variety of distributed energy resources (DERs).DERs include solar panels, wind turbines, energy storage systems (e.g., batteries), electric vehicles, and more.

What are the advantages of DERMS?

DERMS is used to simultaneously communicate, control and coordinate with DER devices in different geographical locations. For example, when excess energy is generated from solar energy during the day and injected into the grid, DERMS can control the excess energy to charge the grid's batteries. When there is a shortage of power on the grid, it can control the batteries to inject energy into the grid and control smart thermostats to lower the temperature of the building, thereby reducing energy demand.

DERMS tracks a large number of individual energy devices.DERMS improves power quality, reduces grid maintenance, and lowers costs. The islanding effect allows DERMS to isolate any resources that are not functioning properly. The islanding effect improves microgrid reliability in the event of a large-scale outage. This means DERMS can provide a reliable supply of power to your home and business during unexpected circumstances such as extreme weather events.

How DERMS works?

Here's a basic rundown of how DERMS works:

  • Data Collection and Monitoring: DERMS collects data from various DERs installed across the distribution system. This includes information on energy generation, consumption, voltage levels, weather conditions, and more.
  • Analytics and Control: Using the collected data, DERMS employs advanced analytics and algorithms to make real-time decisions on how to best manage these resources. It optimizes the operation of DERs to improve system efficiency, reliability, and stability.
  • Coordination and Optimization: DERMS coordinates and optimizes the use of DERs based on grid conditions, energy demand, and other factors. It can perform tasks like adjusting power output from solar panels or batteries, managing energy flow, and responding to grid disturbances.
  • Integration with Grid Operations: DERMS interacts with the larger grid management systems to ensure that the integration of these distributed resources does not disrupt the overall grid operation. It helps maintain grid stability and balance between supply and demand.
  • Decision-Making and Automation: DERMS often employs automation to execute decisions in real-time, ensuring swift responses to changing conditions. It might automatically reroute energy flow, dispatch storage systems, or adjust settings based on predefined protocols.
  • Monitoring and Reporting: Continuously monitoring the performance of DERs is vital. DERMS provides reports and insights into how effectively the resources are being utilized, allowing operators to fine-tune strategies for better efficiency.

What is Demand Response Software

There are various types of Demand Response (DR) software, some of which can be linked to your energy assets for trading in relevant flexible markets. There is also software that clusters DERs together, and the main goal of this type of software is to use energy hardware to balance the grid at peak times.

Demand Response (DR) varies, with some covering multiple areas and others focusing on one. But they all share a common goal of connecting your energy assets to local or national demand response markets.
