Abstract

The increasing energy consumption is stressing utility companies significantly, challenging their ability to meet demand and threatening power system stability. As a result of grid loading, the frequency decreases, exacerbating these issues. End users can mitigate these challenges by participating in energy generation; however, integrating renewable energy sources (RES) introduces variability and uncertainty and necessitates battery energy storage (BES) integration which adds to an increase in the overall cost. Peer-to-peer (P2P) energy trading offers a solution by reducing the additional costs of BES. This paper explores innovative strategies for minimizing the cost of BES through P2P energy trading within energy communities, particularly those utilizing photovoltaic (PV) and wind turbine technologies. This paper will explore the fundamentals of P2P energy trading, highlighting its potential to reduce storage costs by enabling direct energy exchanges between community members to enhance the grid’s stability. Key sessions will cover the technical aspects of integrating PV and wind turbines and the economic benefits of P2P trading. The case study takes residential loads consisting of 15 consumers and 15 prosumers with specific load demands and integrates PV and Wind turbines at 40% of total demand with BES. Then the cost of BES is optimised through P2P energy trading. The result shows the effective strategy for avoiding the challenges related to the BES integration through how P2P trading can revolutionize energy storage economics, paving the way for more sustainable and financially viable energy communities.
