Ancillary services constitute the cornerstone of the power grid. They allow for an efficient system operation, provide resilience to uncertainties and establish safeguards against unprecedented events. Their importance is growing due to the rise of grid decentralisation and integration of intermittent, renewable power sources, which lead to more variability and uncertainty in the system. Today,...

In this paper, the problems of market monitoring and control of ancillary services of future energy systems are presented. We envision that future system operation of electric power systems will evolve into completely unbundled ancillary service markets that are governed by spot price signals. The grid operators need to acquire ancillary services through competitive markets for control of the s...

In a power system, having a high level of renewable energy penetration requires a large amount of ancillary services to balance the supply and demand in real time. Commercial buildings have significant thermal capacity and so offer large potential for providing such services. Recent research has shown that the power consumption of the Heating, Ventilation, and Air Conditioning (HVAC) system can...

This paper discusses various market design options for procuring, pricing and settling Ancillary Services via competitive auctions by an Independent System Operator (ISO). The paper also discusses problems and potential solutions associated with these market design options based on actual experience of operating ISOs. These problems include price volatility and spikes and price reversals for th...

The electricity industry has particular characteristics that create barriers to its successful commercialization. Electrical energy is instantaneously transmitted from generators to end-use equipment according to physical laws rather than commercial contracts. Any blueprint for commercialization must be compatible with these characteristics. The main commercial activities in a restructured elec...

Universities have been putting more emphasis on developing ancillary services in an effort to make them look better and become more attractive to both prospective students as well as financial donors. However, in making the decision as to what level of ancillary services they should administer, universities face the problem of whether they are compromising their academic quality.

Motivated by airline baggage fees, we consider a service provider offering a main service (e.g., transporting a person) and an ancillary service (e.g., transporting a checked bag) that an individual customer may or may not need. We ask whether the firm should bundle the two services and post a single price or unbundle them and price the ancillary service separately. We consider two motivations ...

In this chapter, we propose a method for the utility grid operator and aggregators to coordinate multiple grid-connected electric vehicles (EVs) so as to provide electricpower ancillary services accounting for quality-of-service (QoS) guarantees for EV charging in a multilevel vehicle-to-grid (V2G) system. This method includes applying consensus-algorithm-based distributed control, designing th...
