Distributed Energy Resource Management
- Distributed energy resources (DER), including generation, storage, responsive demand, and microgrids, are impacting the way electric power systems planned and operated.
- DERs with their variability/intermittency (e.g. PV) and time series nature (e.g. storage) can cause potential complex two-way power flow with impacts to power quality, grid capacity, protection, control, etc.
- DERs are at the center of power system transformation/modernization with strong public policy and environmental drivers.
- DERs can be used to provide grid support, including voltage correction, loss minimization, and capacity management as non-wires alternatives.
- Enables new customer-engagement models where customer-owned assets (e.g. solar, storage) can provide grid support.
- Model-based system for maximum accuracy and adapts to real time network topology, even under complex two-way power flow.
- Highly modular and lightweight, “one-feeder-at-a-time”, yet scalable for full enterprise integration.
- Future-proof to dispatch smart inverters and energy storage systems for grid support, whether above-the-meter or behind-the-meter.
HOW GRIDOS DOES IT
- Inputs include the 3Φ AC unbalanced electrical model of the network, with real time network topology, field measurements (e.g. SCADA, AMI), and available volt-VAR devices and DERs (e.g. LTC, voltage regulators, capacitor banks, PV, storage, microgrids).
- Powerful distribution system state estimation (DSSE) for real time DER connection impacts for operations and operational planning, including locational marginal and hosting capacity analysis.
- Multi-objective optimization for theoretically optimal dispatch of volt-VAR devices and dispatchable DERs (e.g. smart inverters, storage).
- Future-proof integration of DERs with microgrid energy management and transactive energy systems.
