Analysis of Renewable Energy and Development Path of New Power System under China’s “Dual-Carbon” Situation

China’s strategic goal of “carbon peak, carbon neutrality” has a huge impact on the new power system. This paper analyzes China’s primary energy consumption, renewable energy proportion, electricity consumption and targets for capacity of photovoltaics and wind turbines. The key development path suitable for China’s new power system are significantly discussed. Results show that it is vital to control the installed capacity of coal power plant strictly, keep the wind power and photovoltaic as main increment, accelerate construction of energy storage and pumped water storage, support nuclear power as base-load supply, strengthen construction of ultra-high voltage (UHV) grid, establish electricity spot market. All those approaches are designated to increase penetration of clean energy and promote reform of the new power system.
