[0002] With the significant increase in the penetration of distributed renewable energy generation equipment, more and more traditional users on the demand side have acquired the ability to independently supply energy, becoming power-sharing participants with both energy supply and energy demand capabilities. Furthermore, IoT technology can build a power-sharing platform for power-sharing participants through information exchange, laying a solid foundation for them to actively and directly participate in power and energy sharing, providing favorable conditions for promoting renewable energy consumption and exploring energy management.

[0003] However, because most power-sharing participants lack the expertise to participate in power sharing and develop power energy docking plans, their decisions often become uncertain and ineffective, lacking flexibility and initiative, negatively impacting the safe and economic operation of the power grid. Existing technologies lack the technical support for power-sharing participants to proactively conduct energy docking during power sharing. They cannot fully leverage the expected contribution value and supply-demand ratio of each power-sharing participant to promote energy docking during the power-sharing process. This reduces the cumulative contribution of power-sharing participants and places significant pressure on renewable energy consumption, leading to severe wind and solar power curtailment and low renewable energy utilization.

The calculation method of the power supply expected contribution value deviation is shown in formula (5): In formula (5), represents the power sharing participant p i As an energy demander, the deviation of the expected contribution value of power supply in the power sharing in the current period t; like When the power sharing participant p i When it is an energy supplier, the calculation method of the expected contribution value deviation of power consumption is shown in formula (6): In formula (6), represents the power sharing participant p i As an energy supplier, the expected contribution value deviation of electricity consumption in power sharing in the current period t.

6. The method for interconnecting power sharing energy taking into account expected contribution value deviation and supply-demand ratio according to claim 5, characterized in that: The method for each power sharing participant to calculate the supply and demand ratio in its power sharing in the current period is shown in formula (7): In formula (7), represents the power sharing participant p i The supply and demand ratio in the current period t, N(t) represents the total number of power sharing participants in the current period t.

7. The method for interconnecting power sharing energy taking into account expected contribution value deviation and supply-demand ratio according to claim 6, characterized in that: The method for each power sharing participant to calculate the renewable energy supply adjustment coefficient in its power sharing in the next period is shown in formula (8): In formula (8), represents the power sharing participant p i According to the deviation of the expected contribution value of power supply in the power sharing in the current period t and the supply-demand ratio, the renewable energy supply in the next period t+1 is calculated. The adjustment factor; The method for each power sharing participant to calculate the renewable energy demand adjustment coefficient in its power sharing in the next period is shown in formula (9): In formula (9), represents the power sharing participant p i The energy demand in the next period t+1 is calculated based on the expected contribution value deviation of power consumption in the power sharing in the current period t and the supply-demand ratio. The adjustment factor.
