| Summary: | Under the guidance of the strategic goal of “carbon peak and carbon neutral”, it is an inevitable choice to accelerate the construction of a new power system with new energy as the main body. As a hub of new energy, Zhou Shan plans to access a large number of new energy during the 14th five-year plan. In order to avoid the intermittent and fluctuating effects of new energy on the AC system, this paper studies several schemes of new energy access to the power system, and analyzes from reliability, auxiliary equipment, loss, investment and so on. Finally, a suitable scheme for photovoltaic access to Yang Shan power grid is recommended.
