Abstract
The Renewable Portfolio Standard (RPS) requires renewable resources to occupy an important proportion in electricity production, but from a practical point of view, market forces have a very deep impact on the renewable energy certificate market and electricity market. In this article, therefore, understand the market power problems in RPS, puts forward the leading edge of the enterprise competition model, focusing on the analysis of different leading enterprise market power in renewable energy and electricity price changes in the price of certificate, according to the specific requirements of RPS at the same time, explicitly different leading enterprise in the empirical analysis of the impact of market power. The final results show that the price of renewable energy certificates is too low, so that the development of renewable energy investment is not sufficient for a long time. However, too high price will affect the incentive signal of investment, resulting in low efficiency allocation of power generation resources in the long term. Therefore, the regulatory authorities should put forward effective market performance monitoring content on the basis of understanding the market changes, so as to ensure the healthy and stable development of renewable energy in RPS.
