摘要：
With the deepening of electricity market reform and the ever-increasing penetration of intermittent renewable energy generation (IREG) units dominated by wind power and solar power generation in the power system, the current full-quantity fixed-price procurement scheme for IREG units will be gradually stepped down as planned, and the IREG units will participate in the electricity market as market competition entities, including the electricity spot market operation. In this context, considering the green certificate trading, a three-layer decision-making model is established to optimize the government subsidy policy for IREG units and guide them to participate in electricity spot market operation. First, the transition mechanism is proposed, and the involved multi-market multi-entity transaction framework is established. Next, a multi-agent three-layer decision-making model considering green certificate trading is formulated aiming at optimizing the contract coverage ratio, maximizing social welfare in market clearing, and optimizing the bidding strategies of generation units in the electricity spot market, respectively. And the market clearing results are used as the interactive data among the three layers. Then, based on the Karush-Kuhn-Tucker (KKT) condition, the three-layer decision-making model is transformed into a mixed-integer linear programming model, so as to improve the solution efficiency. Finally, the feasibility and effectiveness of the proposed transition mechanism are demonstrated through a case. © 2023 Automation of Electric Power Systems Press. All rights reserved.
