Systems and methods for utilization of demand side assets for provision of grid services
Systems and methods are provided, which facilitate operations planning, dispatch, regulation control, and autonomous control performance. The disclosure also facilitates systems and methods for utilization of synthetic primary frequency response, synthetic inertia, regulation and load following/ramping reserve capabilities from Demand Response and Distributed Energy Resources for balancing demand and supply and maintaining frequency levels across a power grid.
1. A method for regulating the electrical grids and grid-connected devices comprising the following steps:
providing a grid operations center server, having a memory containing instructions which, when executed by a processor cause the processor to:
determine the levels of grid services needed from available demand response and distributed energy resources (DR-DER) assets for each time interval increment in the operations planning time horizon;
determine the available capacities and virtual power plant (VPP) costs for each time interval increment;
send a determined capability commitment for grid services to a grid services optimization processor for each time interval increment;
the grid services optimization processor configured to determine the required grid services from each VPP for each time interval;
a grid services management server allocates the grid services assigned to each VPP to individual load control switches and intelligent controllers using secure data communications channels, so that thresholds are output to simple load switches, and thresholds and trigger set-points are downloaded to switches and local controllers for complex loads and distributed storage and generation.
2. The method of claim 1 further wherein a tertiary control processor outputs dispatch base points for generating units and VPPs for each time interval.
3. The method of claim 1 further wherein a secondary control processor provides regulation from both conventional generation under AGC and from VPPs capable of and scheduled for providing regulation services.
4. The method of claim 1 further wherein a primary control processor provides autonomous frequency response in response to grid frequency changes from simple loads, complex loads and distributed storage and generation.
