Does centralized coordination affect energy storage savings?

Centralized coordination of small-scale energy storage systems, such as home batteries, can offer different services to the grid, like operational flexibility and peak shaving. This paper investigates how centralized coordination versus distributed operation of residential electricity storage could impact the savings of owners.

What are the benefits of a centralized energy system?

Residential consumers can accumulate greater savings with a centralized energy system, ranging from 2-5% when operating no technology, 3-11% with Energy Energy Storage Systems (EES) alone, 2-5% with Photovoltaic (PV) alone, and 0-2% with both PV and EES.

How does centralized storage affect electricity costs?

The impact of centralized coordination of storage resources on residential consumers' annual electricity costs generally increases with the level of variable renewable generation capacity in the electricity system while inversely related to the level of flexible supply capacity.

What is distributed energy storage?

Distributed energy storage refers to small-scale energy storage systems located at the end user site that increase self-consumption of variable renewable energy such as solar and wind energy. These systems can be centrally coordinated to offer different services to the grid, such as operational flexibility and peak shaving.

How do demand-side storage resources function?

In a centralized scheduling system, demand-side storage resources are autonomously optimized by consumers. An aggregator coordinates electricity dispatch from Energy Energy Storage (EES) by iterative negotiation with consumers, whose resources it does not know, enabling them to participate in the wholesale market.

Is centralized coordination better than distributed operation of residential solar PV-battery?

The benefits of centralized coordination versus distributed operation of residential solar PV-batteries are discussed. Centralized coordination can offer greater savings to prosumers, particularly under time of use tariffs. However, the value of home batteries depends on the need for flexibility in the energy system in the long term.
