Abstract
The further liberalization of China's electricity market encourages demand-side entities to participate in electricity market transactions. Electric vehicles (EVs) are developing rapidly and have high regulating potential, and are the main force for demand-side participation in the auxiliary service market. Aiming at the problems of dispatching accuracy and economy in EV participation in auxiliary service market, this paper analyzes the bidding strategy and dispatching scheme of EV-storage participation in auxiliary service market, and proposes EV-storage optimal allocation strategy with the goal of economic optimum. In the process of optimal allocation, based on the market rules of third-party subject participation in auxiliary services, the bidding strategy of EV-storage coordinated EV participation in auxiliary services market considering daily load scale changes is designed, while the conditional value at risk (CVaR) method is used to determine the short-term coordinated energy storage capacity and efficiency storage capacity considering the uncertainty of EV response situation; then, based on the annual EV load scale change, the benefit calculation function is constructed by considering various factors such as auxiliary service market revenue, spread revenue, investment cost and market opportunity cost of EV-storage participation in the auxiliary market. Finally, taking EV aggregation participation in the valley-filling ancillary service market as an example, it is verified that the strategy proposed in this paper can effectively improve the responsiveness of EV participation in the ancillary service market and increase the revenue of electric vehicle aggregator (EVA).
Highlights
With the increasing prominence of global resource and environmental protection issues, the traditional energy flow structure is in urgent need of improvement
In this paper, with the objective of maximizing Electric Vehicles (EVs) market benefits, the optimal energy storage allocation problem is studied by analyzing the characteristics and market mechanisms of energy storage coordinated EV participation in auxiliary services
A scenario simulation of EV aggregation participation in North China auxiliary service market in Beijing proves that reasonable energy storage allocation can significantly improve EV participation in auxiliary market benefits
Summary
With the increasing prominence of global resource and environmental protection issues, the traditional energy flow structure is in urgent need of improvement. The reform of China's electricity market has further promoted the interaction between supply and demand, and encouraged the participation of third-party entities in auxiliary services, which is an important means to promote the consumption of renewable energy and improve energy efficiency in the energy internet era. China's new energy vehicles are developing rapidly, and the number of Electric Vehicles (EVs) is expected to reach 60 million by 2030, and the peak charging load will reach 479GW [1]. EVs participation in the ancillary services market has great potential for development, which is important for promoting a high percentage of renewable energy consumption [2], reducing the cost of ancillary services, and maintaining load stability [3,4]. The literature [6] considered EV mobile storage to provide primary frequency regulation control; the literature [7] smoothed out grid load fluctuations through the control of EV mobile storage, and the results proved that EV mobile storage has a large regulation potential to realize
