The Reserve Sharing Mechanism Among Interconnected Power Grids Based on Block Chain

Reserve resources shortage has occurred with the increasing penetration of renewable energy. To share reserve resources and improve operation reliability of interconnected power grids, a reserve sharing mechanism based on block chain is proposed. Probabilistic forecasting scenarios are used to depict stochastic wind and solar generation. Renewable energy curtailment, unserved demand and reserve shortage are considered in the system operation cost. Then Shapley values are calculated as the settlement for external market participants to remunerate reserve capacity, which evaluate the values of the shared reserve resources to the interconnected power grid. Block chain technology is first adopted in reserve sharing for practical implementation to build trust among market participants. Case studies based on the IEEE 57-bus system validate the effectiveness of the proposed mechanism and models.
