In face of the increasingly severe situation of abandoning renewable energy such as wind power or photovoltaic power

an effective trading mode is exchanging electricity between renewable energy generation(REG)and the self-owned power plant(SPP). Through the power exchange platform

SPP transfers their relevant index of energy-generating capacity to REG which are more clean and energy-saving. This paper not only describes the characteristics and economic benefit model of the electricity exchange trading mode

but also designs trading rules including matching rules

executing rules and clearing rules. And several enterprises in Gansu Province are taken as a pilot. It is validated that the mode under discussion is able to greatly mobilize the enthusiasm of participants to achieve renewable energy issuance and emission reduction. Finally

to solve the related pilot issues

improvement measures and application prospects of the trading mode are explored. This work is supported by National Key Technologies R&D Program(No. 2015BAA01B04)and State Grid Corporation of China.
