Improved Generation Right Trading for Self-supplied Power Plants

In the context of deepening energy transition and reform of power system, it is necessary to study the mechanism to fully mobilize the interaction between self-supplied power plant and power grid, and participate in the consumption of renewable energy in a market-oriented way. The paper innovatively proposes an improved generation right mechanism of self-supplied power plants engagement in renewable energy consumption, establishes the cost-benefit models before and after trading, and quantitatively analyzes the tradable bidding strategy interval and the transaction clearing mode under high-low matching. The effectiveness of the models is verified by the calculation example of IEEE-30 node. The engagement of self-supplied power plants in the generation right trading changes the self-consumption mode of producer and consumer, and boosts consumption of renewable energy.
