Optimization Operation Model of Wind-PV-hydro-Thermal Integrated System in the Carbon Electricity Market

Aiming at the current reform and construction of the carbon electricity market and low-carbon transformation of the energy, this article proposes an optimization operation method and market bidding model for wind, wind-PV-hydro-thermal integrated system. Firstly, the quota allocation mechanism for thermal power units and the development and accounting method for renewable energy CCER projects such as wind, PV, and water are analyzed. Firstly, the carbon quota allocation mechanism for thermal units and the calculation method for renewable energy CCER projects were analyzed. And the transaction rules for different power sources participating in electricity trading, carbon quota trading, and CCER trading were briefly introduced. Furthermore, based on the characteristics of wind power, PV, hydropower and thermal power, the complementary system output model and complementary indexes were constructed, which ensure the stability and schedulability of total output. Based on the above, a market bidding model for complementary system is proposed in the carbon electricity market for the comprehensive cost-effectiveness of carbon electricity. Finally, through case simulation, the optimized output curve and bidding strategy of the multi energy complementary system are obtained, that ensures the complementarity and economy while reducing the carbon emission.
