Abstract
China’s renewable energy power has developed rapidly in recent years. Evaluating the external benefits of renewable energy power can provide a reference for the Chinese government to set diverse development goals and to implement differentiated supporting policies for different renewable energy power types, which can promote their sustainable development. In this paper, a hybrid MCDM method was applied to evaluate the external benefits of China’s renewable energy power. Firstly, the impacts of renewable energy power accessing the power grid for multiple stakeholders in the electric power system were analyzed. Secondly, the external benefit evaluation index system for renewable energy power was built from the economic, social and environmental factors, based on the concept of sustainability. Then, the basic theory of the hybrid MCDM method employed in this paper was introduced in two parts: the superiority linguistic ratings and entropy weighting method for index weight determination and the fuzzy grey relation analysis for ranking alternatives. Finally, the external benefits of wind power, solar PV power and biomass power were evaluated. Taking a regional electric power system as an example, the results show that PV power has the greatest external benefit, followed by wind power and biomass power. Therefore, more policies supporting PV power should be put in place to promote the harmonious and sustainable development of the whole renewable energy power industry.
Highlights
In 1987, the United Nations World Commission on Environment and Development (WCED)published a report entitled “Our Common Future”, which proposed a term, “sustainable development” [1].Building a resource-saving and environment-friendly society is a strategic mission for China’s economic and social development [2]
The rest of this paper is organized as follows: Section 2 analyzes the impacts of renewable energy power accessing the power grid for multiple stakeholders in the electric power system; the external benefit evaluation index system of renewable energy power will be built in Section 3; Section 4 introduces the basic hybrid fuzzy multi-criteria decision making (MCDM) theory used in this paper; the external benefits of three renewable energy power types, namely wind power, solar PV power and biomass power, will be evaluated in Section 5; and Section 6 provides conclusions
(1) After analyzing the impacts of renewable energy power accessing the power grid on conventional power generation enterprises, power grid companies, electric power consumers and the environment as well as society, the external benefit evaluation index system for renewable energy power in China was built from economic, social and environmental factor based on the concept of sustainability, using 11 indicators: power grid company revenue reduction, power generation enterprise cost increase, electric power consumer expenditure increase, economic growth promotion degree, energy security enhancement degree, employment increase, fiscal tax increase, technical innovation promotion degree, environmental pollutant emission reduction, water savings and bird and vegetation damage
Summary
In 1987, the United Nations World Commission on Environment and Development (WCED). published a report entitled “Our Common Future”, which proposed a term, “sustainable development” [1]. An external benefit evaluation on renewable energy power accessing the power grid can identify the comprehensive impacts of different renewable energy power types on multiple stakeholders, which can act as a reference for Chinese government when setting diverse development goals and implementing differentiated supporting policies for different renewable energy types. It can promote the sustainable development of the renewable energy power industry in China. The rest of this paper is organized as follows: Section 2 analyzes the impacts of renewable energy power accessing the power grid for multiple stakeholders in the electric power system; the external benefit evaluation index system of renewable energy power will be built in Section 3; Section 4 introduces the basic hybrid fuzzy MCDM theory used in this paper; the external benefits of three renewable energy power types, namely wind power, solar PV power and biomass power, will be evaluated in Section 5; and Section 6 provides conclusions
