Research on the investment policy of energy storage and other flexible adjustment resources under the scenario of high proportion of new energy

Abstract

With the increasing proportion of new energy in my country's energy structure, new energy will gradually replace thermal power generation as the main energy supply in the future. However, because the volatility and intermittency of new energy sources have also seriously aggravated the uncertainty of the power system, it is necessary to add flexible resources such as energy storage systems to participate in long-term planning. Under the high-proportion of new energy scenario, the huge uncertainty of the source and load also makes the traditional method of assessing the capacity of new energy consumption from the perspective of capacity no longer applicable. To meet the energy policy requirements, traditional energy and new energy resources must be considered together. In order to solve the above-mentioned problems and challenges related to the operation mode of the power system in the future, this article will discuss how the system can achieve its own balance of supply and demand through the rapid and accurate regulation of flexible resources, while meeting the diversified energy supply and demand requirements. How to conFigure the energy system, and what strategy should the power system use to deal with it.
