The Experiences and Practices on Market with Large-Scale Renewable Energy Grid Integration

Abstract

In order to accommodate renewable energy, the power system should regulate the power supply of the traditional power plant according to the power of the renewable energy to achieve the balance of supply and demand of the whole system. It can be seen that one of the challenges of large-scale renewable energy grid-connected is the balance of supply and demand of the multi-party collaborative maintenance system of the power system. Due to the intermittent, random and fluctuation characteristics of renewable energy, large-scale renewable energy integration and participation in electricity market have a great impact on the operation of the electricity market. There are many related researches in the world, and many scholars have done a more in-depth study on this. At present, relevant research mainly focuses on the optimization operation of renewable energy power systems, promoting policies, technical means and market mechanisms for renewable energy consumption. During the last few decades the power market reforms are executed in so many countries due to the development of renewable energy. Traditional electricity market mechanism has been unable to adapt to the situation of large-scale development of wind and PV power in China, and the new power market mechanism has not been established, and market consumption has become the biggest bottleneck in the development of renewable energy. This paper analyzes the impact of renewable energy participation in electricity market and takes Germany, Northern Europe and Spain as typical example, introduces the countermeasures of mature foreign power market, and finally puts forward inspiration and reference.
