A Review of the Value of Aggregators in Electricity Systems

Electricity systems are currently facing significant changes as a result of the deployment of information and communication technologies (ICTs), power electronics, and distributed energy resources (e.g., gas-fired distributed generation, solar PV, small wind farms, electric vehicles, energy storage, and demand response). Given the small scale of these technologies, many industry stakeholders claim that aggregators can create economic value by enabling DERs to provide these services at scale.
