Generation-network-storage Collaborative Planning of Jiangsu Power Grid Towards Carbon Neutrality

Under the goal of carbon neutrality, high shares of renewable energy will be integrated into power systems rapidly. However, as the largest electricity consumption province, Jiangsu faces considerable challenges in transforming the energy supply structure because of renewable energy's intermittent and variable nature. The generation, transmission network and storage need to be coordinated to facilitate carbon emission reduction. In this paper, the carbon-neutral path of the Jiangsu power grid is investigated using Generation-network-storage collaborative planning (GNS-CP). A multi-year and multi-area GNS-CP is conducted with the Generation & Transmission Expansion Planning (GTEP) tool developed by Tsinghua University. Besides, two sensitivity analyses are carried out to investigate the impacts of receiving-end and regional differentiation features of Jiangsu power grid.
