Digital twin advanced distribution management systems (ADMS) and methods
| DWPI Title: Controller for controlling power system equipment and distributed energy resources in photovoltaic inverters for providing e.g. peak shaving services for electrical power grid, has optimization module for providing control commands to power system equipment or distributed energy resources system |
| Abstract: Advanced Distribution Management Systems not generally optimize over the entire feeder because there are few high-fidelity distribution circuit models and real-time distribution-connected sensors are rare. The limited observability at the distribution level makes it difficult to globally optimize distribution operations and issue control setpoints to power systems equipment or Distributed Energy Resources (DER) to perform grid-support services. For example, setpoints can be issued to DER based on results from an optimization module that incorporates a static or time-series feeder simulation. Feeder simulation initial conditions are populated with photovoltaic (PV) and load forecasts, state estimation results, and/or digital twin measurements or state output. The real-time (RT) digital twin runs a model of the feeder to generate state estimation pseudo-measurements since there are limited live feeder measurements. |
| Use: Controller for controlling power system equipment and distributed energy resources in electrical power system such as photovoltaic (PV) inverters for providing grid support services e.g. voltage regulation services, peak shaving services and loss minimization services for an electrical power grid. |
| Advantage: The controller reactively controls power system devices and distributed energy resources in an electrical power grid in real-time. |
| Novelty: The controller has a digital twin simulation module for receiving inputs from sensors in an electrical power system to update a digital twin simulation module while simulating an electrical power system. The optimization module receives inputs from a state estimation module representing current operational conditions of the electrical power system. The optimization module provides control commands to a power system equipment or the distributed energy resources in the electrical power system. The digital twin simulation module comprises a database of historical operations of the electrical power system, where the control commands are selected from a group consisting of demand response signals, Institute of Electrical and Electronics Engineers (IEEE) 1547-2018, an active power setting, a reactive power setting, a constant power factor, a voltage-reactive power mode, on/off commands and other analog or digital control set points. |
