Microgrids/local energy systems Actors and business models for flexibility in distribution grids A systematic review of machine learning techniques related to local energy communities 2022 2/FINE

This subtopic is about the techno-economic evaluation of microgrids and local energy communities (LECs). One of the main economic challenges in microgrids is to establish business models that can enable participation in the markets and offer services. In the long run, together with technical advancements and regulations, this will make the microgrids a solution to provide more flexibility and efficient and resilient operation in the distribution grid. On the other hand, other challenges are related to the regulations for how to sell and buy electricity locally in LECs. Some concepts are still in the early stages, such as peer-to-peer energy trading schemes.

In CINELDI, a techno-economical evaluation at the Skagerak EnergiLab was performed [1]. Here, the performance of an existing infrastructure, which is a football stadium with solar panels and batteries, under a variety of operation strategies for peak-shaving, self-consumption maximization, and energy arbitrage was tested. A Model Predictive Control (MPC) for the Skagerak EnergiLab is also proposed in [2]. The control seeks to find a trade-off between control objectives and decrease the operation cost while constraints in a probabilistic sense are satisfied.

In CINELDI, there is also research related to peer-to-peer trading. For example, reference [3] explored the market value of batteries using local electricity trading. End-user economic benefits are analyzed and compared with traditional schemes. In [4], a framework was proposed to integrate prosumer communities into the existing electricity market.

CINELDI results can show how technical-economic analysis can be done and suggest new business models that can assist the implementation of new microgrids [1]. Moreover, the evaluation of peer-to-peer trading can also show the potential economic benefit in local energy communities [5].
