A Game-Theoretic Approach for Enabling Peer-to-Peer Sharing of Rooftop Solar Energy

Rooftop solar (RTS) has emerged as a widely utilized mode of decentralized Energy resource. Net metering and feed-in tariffs are among the preeminent examples that compensate prosumers for injecting their excess solar generation into the grid. However, the real value of this clean source of power is not always ensured by these mechanisms, and the consumers remain under-compensated for the value they bring to the system. Peer-to-peer Energy Sharing Mechanism (P2PESM) with rooftop Solar Energy can provide a level-playing field for prosumers by providing appropriate prices for their excess Energy through adequate Energy and cost-sharing mechanism, With prices remaining in regulatory limits. The above-mentioned mechanism can incentivize residential consumers to adopt RTS. This paper presents a game theory-based approach wherein cooperative game theory-based shapley value approach is used to find the most appropriate internal buying and selling prices with a fair distribution of benefits among consumers, with a proper performance index for an analysis carried out for an institutional campus-based set up in India.
