Abstract To promote the renewable energy development and reduce the power grid safety risk, promoting the power local consumption generated by distributed photovoltaic energy has received increasing attentions. Moreover, with the power market development, integrating the power market trading with distributed photovoltaic energy is a trend in China. Aiming to these targets, the paper designs a business model integrating investment and consulting services into distributed photovoltaic energy system. First, to encourage the market trading and promote the power local consumption, the double layer power sale platform is designed consisting of both B to B and B to C platforms. And a discount power sale price for local consumption is carried out. In the power platform, power contracts with a punishment for power gap are signed before the power consumption. Second, the consulting services are cited to reduce the power gap caused by power market trading, consisting of power output, power load and annual new installed capacity prediction. Third, considering the local users' power demand increase brought by the discount power sale price, a dynamic investment is integrated in the business model. Moreover, the simulation model and a comparative analysis model of stakeholders' benefits of new business model is constructed. Finally, an empirical analysis is conducted. The results show that the new model not only can promote energy local consumption, improve environment quality, ensure power grid safety, but also increase distributed energy investors' benefits, and reduce users' electricity expenses and government subsidies. Graphical abstract Image 1 Highlights • The dynamic increment investment model of distributed generation is designed. • The simulation model of new distributed generation business model is set up. • Based on the consulting services, the investment mode and sale mode are combined. • The interactive consultation service module between supply and demand is designed. • The stakeholders' benefits under the new business model is calculated.

In recent years, with the large-scale and centralized development of the wind power industry in China, wind power curtailment has become increasingly serious. In order to promote wind power consumption in China, this paper designs four kinds of feed-in tariff (FIT) mechanisms: a double-track FIT mechanism based on a ratio, a time-of-use benchmarking tariff mechanism, a net back pricing mechanism based on the inter-provincial wind power consumption market, and an FIT mechanism based on negotiation. Then, we establish a benefit distribution model to analyze the wind power stakeholders’ benefits. Finally, based on the four kinds of FIT mechanisms and the benefit distribution model, we propose the best FIT mechanisms for the various electricity market circumstances in China, in order to provide a reference to formulate wind FIT, to promote the consumption of wind power and to advance the sustainable development of renewable energy in developing countries.

Renewable energy has become the world's strategic choice to solve environmental pollution, address the energy crisis and achieve social sustainable development. The establishment of a regulatory system coincides with the development stage of renewable energy and electricity market operation is significant in standardizing the market competition and guaranteeing healthy development of renewable energy in China. This paper analyses the current situation of renewable energy development and the existing renewable energy regulation system in China, pointing out that the main problems restricting renewable energy development are institutional mechanisms and market factors. The existing regulatory mechanisms also have deficiencies, such as the inclination towards economic regulation and the lack of a market adjustment mechanism. This paper proposes that China should comprehensively consider the renewable energy development stage, electricity market trading mechanisms and other factors in electricity regulatory requirements when policy making, actively exploring a new renewable energy regulation model adapted to different development phases. In addition, this paper suggests China's regulatory policy path based on the forecasting of renewable energy developing models. [ABSTRACT FROM AUTHOR]
