Multi-market Coupling Trading Simulation of Electricity Green Certificate and Excess Consumption Under New Renewable Portfolio Standard

doi:10.16182/j.issn1004731x.joss.21-0699

Abstract

Abstract:

In order to clarify the multi-scale market coupling interaction relationship of electricity, green certificate, excess consumption under the renewable portfolio standards (RPS), the system dynamics is introduced, and the interactive trading model is constructed and simulated. Taking the logistics transformation of three market transaction targets as the clue, this paper designs a multi-scale market coupling transaction framework, constructs the complex causality of coupling transaction based on system dynamics method, and analyzes the impact of RPS on the revenue or cost of market participants. Simulation results show that under the new RPS, the electricity price will gradually decline, the transaction price of green certificate will be depressed by the consumption certificate, and the transaction price of green certificate will eventually become equal. The new RPS will reduce the market income of renewable energy generators and the fluctuation of electricity cost of users, and increasing the proportion of RPS will slow down the decline rate of both.

Key words: renewable energy trading, electricity market, excess consumption, green certificate
