DER Management Solution

Energy trends of renewable penetration and decentralization of generation assets create new industry challenges. These challenges include integration, coordination, and maximizing return-on-investment (ROI) on distributed energy resources (DERs), while providing network reliability and flexibility.

GE's GridNode Distributed Energy Resources (DER) Management solution enables utilities and developers to easily integrate renewable energy resources

The GridNode DER Management solution includes the control and automation functions to manage active and reactive power, power factor, and voltage at the point of interconnection for your renewable energy resources.

Customer Outcomes

  • Improve Reliability by exploiting renewable generation capabilities in order to provide optimal support to the grid
  • Ease of deployment by utilizing GE’s configurable GridNode DER Management Solution
  • Increased revenue through equitable dispatch across renewable generation assets and providing the capability to provide ancillary services to the grid such as Reactive Power support
  • Energy cost reduction through a solution that can efficiently manage, optimize and integrate low cost renewable onto your grid
  • Life extension by reducing the number of operations on distribution level voltage transformers and capacitor banks through the optimal and flexible dispatch of your renewable generation assets

What is a Distributed Energy Resource (DER)

"A Distributed Energy Resource (DER) is any resource on the distribution system that produces electricity and is not otherwise included in the formal NERC definition of the Bulk Electric System (BES)". ~ NERC . Distributed Energy Resources are sometimes referred to as Distributed Generation, Distributed Energy, or Decentralized Energy and typically consist of renewable energy sources such as solar, wind, and storage.

Challenges with Integrating Renewables

  • Reliability issues associated with connecting DERs onto the grid
  • Coordination, Flexibility and Control of DER resources from different vendors for optimal and/or equal market participation
  • Maximizing Return on Investment (ROI) through energy market participation
  • Cost of Ownership and CAPEX
  • Stress on existing network infrastructure

Benefits of GE’s GridNode: DER Management Solution

  • Increase Reliability and Flexibility – Increase functionality and grid support capabilities, monitoring, and control
  • Reduction in CAPEX – Life Extension of Assets, Ease of Operation
  • Increase Revenue – Ability to provide grid support (Reactive Power)
  • Increases Asset Life – Reduced OLTC Operations

GridNode DER Management Solution is a flexible and scale-able platform that incorporates various dispatch modes and control capabilities to easily integrate renewable energy onto the grid. The GridNode platform is vendor agnostic having the capability to integrate GE and 3rd party devices and assets.

Dispatch Modes

GridNode: DER Management Solution, has the capability to dispatch commands to the connected DERs in one of the modes below in order to achieve the provided setpoint at the point-of-interconnection (POI).

Voltage
Reactive Power
Active Power
Power Factor

The GridNode: DER Management Solution considers the network limits and parameters and the individual DERs capacities and constraints when dispatching commands to each DER. In addition, the GridNode solution is capable to controlling a tap changer if required to obtain the desired value at the point of interconnection (POI).

Control Capabilities

Equitable Dispatch
  • Ability to equitable dispatch the setpoint provided by the operator or DMS in an equitable manor, considering the system limits, across all DER assets.
Ramp-Rate Control
  • Ability to control the ramp rate of the intermittent renewables connected to the system.
Feeder Controls
  • Ability to integration feeder controls and monitoring into the solution
Volt-Var Control
  • Ability to issue raise and lower commands to OLTCs, when the DER capabilities are exhausted

Business Model

As with most projects a microgrid project requires effective planning, analysis, and execution. Projects can range from large scale new installations consisting of engineering procurement, and construction of buildings, new DERs, electrical and mechanical equipment, protection and controls, as well as services to retrofits of existing systems with new microgrid controls. When required, GE partners with industry leaders to develop and design a system around our customers desired outcome. This approach enables GE to deliver a full turn-key solution.

Customer Case Study: Nice Grid, France

FIRST MEGAWATT SCALE SMART SOLAR DISTRICT

Grid Solutions provides a smart energy management solution which controls and optimizes the full range of local energy resources available to solar districts in real time through an array of flexible solutions that are compared and incorporated into the grid. The energy manager monitors information on conditions affecting network operations—such as sun forecasts, consumption patterns, and technical issues— and activates these flexible solutions based on aggregated customers flexibilities given by EDF. Electricity supply is optimized, renewable energy integration is optimized and the overall carbon footprint of the district is reduced, providing a better quality of life.
