Equilibrium Decision Making in Power Supply Chain Network Based on RPS Considering Tradable Green Certificates

Abstract

The development of renewable energy has attracted widespread attention in the context of the synergistic promotion of the “dual carbon” policy and the power market-oriented reform. Based on this, this paper focuses on the coupling of renewable energy portfolio standard (RPS) and tradable green certificates to participate in the power market. The network equilibrium model of power supply chain considering green certificate trading under RPS is established, and the equilibrium state of power supply chain is obtained by using Nash equilibrium and variational inequality theory, which is solved by using modified projection algorithm. The results show that: the stricter RPS restricts the flow and profit of the power supply chain, but favors the consumption of renewable energy; the social benefit increases and then decreases with the increase of RPS, and there exists a value of RPS that makes the social benefit optimal during the implementation of the RPS policy.
