A review on promoting share of renewable energy by green-trading mechanisms in power system

In order to promote the development of renewable energy power generation, many countries have issued corresponding policies. Meanwhile, some green-trading mechanisms have been implemented in power industry. And this paper has mainly presented a review on promoting share of renewable energy by green-trading mechanisms in power system with a focus on promotion effects of three mechanisms: feed-in tariff, renewable portfolio standard and emission trading scheme. Apart from a review, summaries, comparisons, and an outlook for future study are also presented. Our review suggests that feed-in tariff and renewable portfolio standard can effectively increase the share of renewable energy power and lead to renewable resource diversity. In addition, emission trading also provides stimulus for development of renewable energy besides mitigation of carbon emission.
