Market Transaction Model Design Applicable for Both Plan and Market Environment of China’s Renewable Energy

Abstract

China’s electricity market is undergoing a rapid development stage from plan to market and will exist in plan and market models for a long time. Based on the status quo of China’s power plan and market in-depth, this paper has studied and put forward a kind of market transaction mechanism adapted to the plan and market models of China. The mechanism arranges a priority generation plan first to match the priority electricity plan. Especially for renewable energy generation output greater than planned value, it carries out priority arrangement of renewable energy generation to guarantee its reliable consumption. Then medium- and long-term market transactions and incremental spot market transactions are carried out. This paper detailed design operational processes such as priority plan, medium- and long-term, spot (i.e., day-ahead, intraday, and real time), auxiliary services, and balance stages. Finally, based on actual data of the provincial electricity market, the calculation and analysis are carried out to verify that the method proposed in this paper can effectively reduce market imbalance and promote renewable energy consumption, which has a certain practical value for China’s electricity market development.

A Joint Optimization Approach on Monthly Balancing Mechanism and Unit Maintenance Scheduling

“…China's medium and long-term power market is currently transitioning from contract-based trading to spot market trading [1][2].The monthly dispatch plan for new energy generation is significantly impacted by uncertainties in demand, wind power, photovoltaic, and maintenance plans for conventional thermal power units [3][4]. Given the uncertainties surrounding unit maintenance and supplydemand, it is crucial to conduct joint optimization dispatch of monthly generation and maintenance based on deviation power quantity treatment in the medium to longterm electricity market in China.…”

Credibility Theory-Based Information Gap Decision Theory to Improve Robustness of Electricity Trading under Uncertainties

“…In light of the global imperative to achieve "carbon neutrality," particularly in China, and acknowledging the pivotal role of electricity as a primary secondary energy source, the low-carbon operation of electricity has become a critical concern [1]. While renewable energy sources offer the promise of clean and abundant power, challenges persist, notably encompassing the issues of substantial market volatility and significant deviations in predictive accuracy [2]. The modern power industry, propelled by deregulation and the evolution of electricity market dynamics, has engendered a competitive landscape for global power entities.…”

Improving the quality of project management at energytech through marketing in support of sustainable and environmental development of energy economics

“…EnergyTech is a promising mechanism through which entrepreneurship can and actively supports the environmental development of the energy economy (Azam et al, 2022;Javed et al, 2022;Li et al, 2022;Tang, 2022). EnergyTech refers to advanced technologies in the energy sector introduced by both energy producers (energy companies) and consumers (urban power supply networks, businesses, and households) (Popkova et al, 2019;Popkova and Sergi, 2021).…”
