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 (“DERs”) are being adopted throughout the world. Aggregators are lauded by some as critical in enabling DERs to provide these valuable electricity services at scale; in this light, regulatory and policy bodies are discussing the role of aggregators and even the need to support their market entry.
If problem linearization is accepted, the energy hub formulation is an elegant way to describe energy flows in a synthetic way, and other aggregation concepts such as input–output representations, Microgrids, and VPP can all be modeled through it.
Aggregation as a tool for managing coordination issues Power system operators (ISOs or TSOs) are required to dispatch generation, storage, or demand response resources to match supply and demand at all times. Traditionally, these resources have taken the form of a discrete set of large and easy-to-centralize resources.
1.1. Defining aggregators Aggregation is defined here as the act of grouping distinct agents in a power system (i.e. consumers, producers, prosumers, or any mix thereof) to act as a single entity when engaging in power system markets (both wholesale and retail) or selling services to the system operator (s).
The EU strategy on energy system integration promotes a greater direct electrification of end-use sectors and involves various existing and emerging technologies, processes and business models, such as ICT and digitalisation, smart grids and meters and flexibility markets.
In this context, in fact, significantly important and widespread cases of MES are the ones based on multi or polygeneration, which can be defined as the combined production of multiple energy vectors (e.g., electricity, heat, and cooling), from a unique source of fuel.
