6 FAQs about [Energy Storage Station Aggregator]

Are energy storage aggregators Pareto-inefficient?

This paper studies two generally overlooked aspects related to aggregators of energy storage: i) the relationship between the aggregator and its constituent storage units and ii) the aggregator's effect on system welfare. Regarding i), we show that short-term outcomes can be Pareto-inefficient: all players could be better-off.

Are profit-seeking energy storage aggregators good or bad?

Regarding ii), we first show that a profit-seeking energy storage aggregator is always beneficial to the system when compared to a system without storage, regardless of size or market power the aggregator may have. However, due to market power, a monopolist aggregator may act in a socially suboptimal manner.

What is an aggregator in a power system?

In a power system, an aggregator is a grouping of agents (i.e., consumers, producers, prosumers, or any mix thereof) that acts as a single entity when engaging in power system markets (both wholesale and retail) or selling services to the operator.

Do aggregators and storage units cooperate?

In practice, however, aggregators and storage units are likely to engage in long rather than short-term relationships. Using Nash Bargaining Theory, we show that aggregators and storage units are likely to cooperate in the long-term.

Where can aggregators sell electricity?

Aggregators can then sell electricity via an electricity exchange, in the wholesale market, or through procurement by the system operator. The brief focuses on the various services that aggregators can provide to support power system transformation and the integration of VRE.

Will energy storage provide flexibility and regulation services in future power systems?

Abstract: With the growing penetration of renewable energy and gradual retirement of thermal generators, energy storage is expected to provide flexibility and regulation services in future power systems. Battery is a major form of energy storage at the demand side.
