Distributed Energy Resource Management (DERMS) Features
Demand Response Pre-Planned Events
This feature adds a new web-interface to manage strategies (templates) and events for dispatch schedules controlling demand response devices. Thermostats and other demand response resources for supported head end systems will be modeled as controllable demand response devices in NMS that are grouped at the service transformer for each service provider.
Events are created from strategies. Each event/strategy will have a type. The type will indicate the purpose of the event and will have validation of program rules including scheduling restrictions and priority. With this initial release there will be three event types:
• Economic Event - Events that dispatch DER because the cost of dispatching DR is less expensive than generation. Economic events must be scheduled on a day-ahead basis.
• Reliability - Events intended to mitigate forecasted constraints on the grid. Reliability events must be scheduled on a day-ahead basis.
• Emergency - Events required to mitigate unforeseen grid constraints. Emergency events can be scheduled immediately and will cancel reliability or economic events that have already been scheduled if the same resources are being utilized.
A strategy manager will be able to create and manage a library of strategies. A strategy will consist of staged dispatch groupings. The strategy will have a header, which will reflect the area the strategy is affecting, the purpose of the strategy, and the type of the strategy. The strategy manager will be presented with a peak load forecast and a corresponding curve accounting for DR response for a peak-load day.
An event nominator will be able to select a strategy and create and nominate an event for scheduling. They will start from the strategy but can make modifications to the event based on forecasted system needs. They will be able to review a day ahead load forecast and corresponding forecast including the DR resources.
An event scheduler/manager will see a list of nominated events and will have the option to accept or reject each nominated event. After accepting an event the plan will be sent to Live Energy Connect (LEC) which will communicate to each of the involved demand response vendor head end systems.
