Firstly, the situation and challenges of China’s power green development is analyzed. On this basis, the power green development models are categorized into two typical research objects, which are multi-energy synergy mode, represented by integrated energy systems, and multi-energy combination mode with clean energy participation. The key points of the green power development model with the consumption of new energy as the core are reviewed, and then China’s exploration of the power green development system and the latest research results are reviewed.

Academic Editor: Erik Gawel Received: 6 December 2014 / Accepted: 4 February 2015 / Published: 17 February 2015 Abstract: In 2009, the implementation of feed-in tariff (FIT) and attractive public subsidies for onshore wind farms aroused great investment enthusiasm and spurred remarkable development of wind power in China. Meanwhile, rapid learning-by-doing has significantly cut down the cost of wind turbines and the capital cost of wind farms as well. Therefore, it is the right time to examine the appropriateness of the existing FIT policy for wind power in China. In this paper, we employ the analytical framework for levelized cost of electricity (LCOE) to model the generation cost of wind power. Results show that the existing FIT policy is attractive to investors, but serious curtailment and turbine quality issues could make wind power unprofitable. Meanwhile, rapid substantial decreases in the cost of wind power have made it competitive to coal power in 2013, implying that it is possible and necessary to reform the FIT policy for new wind farms.

ISBN 978-1-78467-019-1 i Abstract Wind power in China has experienced significant growth since the beginning of this century. Total installed capacity has increased almost 300 fold – from 346 MW in 2000 to 91,413 MW in 2013. This rapid development has had two major drivers: • First, the excellent wind power resource in China, especially in the north of the country, and the increasing competitiveness of wind generation worldwide. • Second, favourable government policies such as: mandatory targets for major power generators in relation to renewable energy; the decentralization of plant approval rights; and feed-in tariffs for wind generation. Along with the development of domestic wind turbine manufacturing capacity, these factors have stimulated the growth of wind power over the past 10 years or so. However, this rapid development has itself created new challenges. In particular, wind power has not been fully integrated into the electricity system as a whole, as the growth of wind generation capacity has not been matched by a corresponding growth in transmission capacity.

These reports were well received by readers both at home and abroad, and we have similar expectations for the publication of China Wind Power Outlook 2010. As a new wind power report was expected by people in the industry, CREIA organised experts from both China and overseas to edit and publish China Wind Power Outlook 2010 with the support of Greenpeace and GWEC. Our aim is to satisfy readers’ desire to understand the latest situation on wind power development in China. China Wind Power Outlook 2010 includes the main features of previous reports and some elements from GWEC’s analysis of global wind energy, and tries to reflect the situation, characteristics and prospects for both global and Chinese wind power. The report covers strategic energy demand and resources, market capacity and equipment, market environment and policy, environmental issues and climate change, a historical perspective and prospects for the future. To provide a comprehensive overview for readers, we have tried to analyze and interpret all the main issues for wind power development in China in terms of both the global context and the country’s broader energy development strategy.

The development of the wind energy industry presents interesting policy questions. In the context of China, in additional to national energy policies, provincial policies were designed and implemented to stimulate the growth of wind power. This paper examines factors, especially provincial wind energy policies, in driving the growth of wind power capacity in the Chinese provinces. Statistical analysis with a longitudinal data set for wind power capacity in Chinese provinces from 2001 to 2012 reveals that the adoption of wind energy policies and a general energy plan at the provincial level are having positive effects on the growth of wind capacity in Chinese provinces. Keywords: wind power; policy designs; wind capacity; policy evaluation 1. Introduction China has witnessed dramatic economic development during the last few decades, with the gross domestic product (GDP) growing at a yearly rate of approximately 10% [1].

To ease the situation, greater use of wind energy in China could be the solution for energy conservation and sustainable environment in the long run. This paper describes the presentation of wind power in China, which covers distribution, bases, installed capacity, power generation from the spatial perspective and the environmental benefit. In addition, grey model (GM(1,1) ) and scenario analysis are employed to forecast the installed capacity in China from 2017 to 2025, then the evaluation of two methods is presented. By this research, the results are shown as the following: (1) the North region has great wind energy with 2500–3000 giga watt (GW) and the offshore wind energy in the Southeast is abundant; (2) the Inner Mongolia base located in
