Variable renewable energy (VRE) is not yet meaningfully participating in U.S. ancillary services (AS) markets. VRE participation AS markets could provide a new source of revenue for resource owners to offset declining and capacity values tool power system operators address emerging constraints. This paper uses price-taker dispatch model historical prices estimate the economic value standalone h...

Air-conditioning loads (ACLs) are among the most promising demand side resources for their thermal storage capacity and fast response potential. This paper adopts the principle of market-based control (MBC) for the ACLs to participate in the ancillary services. The MBC method is suitable for the control of distributed ACLs because it can satisfy diversified requirements, reduce the communicatio...

Utility restructuring, technology evolution, public environmental policy, and expanding power demand are providing the opportunity for microturbines and fuel cells to become important energy resources. Deregulation has begun to allow for the provision of various ancillary services, such as load-following. In order to investigate the ancillary services ability of these units in distribution syst...

With the emergence of electric vehicle (EV) era in which vehicle’s embedded batteries can be exploited for grid support purposes, role EVs participating ancillary services via vehicle-to-grid (V2G) technology cannot disregarded. Although there are many forms services, most common delivered by frequency regulation, contingency, inertia, and voltage regulation. Numerous research studies have been...
