Flexibility Analysis for Smart Grid Demand Response
It provides a structured approach for quantifying flexibility in smart grid demand-side management, but the contribution is incremental as it adapts existing standards and formulations.
The paper develops a methodology for assessing electrical load flexibility in buildings for demand response, based on flexibility formulations and optimization, and demonstrates it on a pilot site.
Flexibility is a key enabler for the smart grid, required to facilitate Demand Side Management (DSM) programs, managing electrical consumption to reduce peaks, balance renewable generation and provide ancillary services to the grid. Flexibility analysis is required to identify and quantify the available electrical load of a site or building which can be shed or increased in response to a DSM signal. A methodology for assessing flexibility is developed, based on flexibility formulations and optimization requirements. The methodology characterizes the loads, storage and on-site generation, incorporates site assessment using the ISO 50002:2014 energy audit standard and benchmarks performance against documented studies. An example application of the methodology is detailed using a pilot site demonstrator.
