Driven by the goal of "carbon peaking and carbon neutrality"

the construction of large-scale wind power and photovoltaic bases is accelerating

and the proportion of new energy access is rising rapidly. The proportion of new energy installed capacity in China has reached 30%

and the actual reliable capacity is only 5%

how new power systems with new energy as the main body can achieve safe and stable operation under the premise of economic feasibility has become a key research direction. The power system with thermal power as the base load has been operating safely and stably for many years and has important reference value for the construction of new power systems. This article proposes that taking into account the economic investment on the power side

the wind

solar

and hydrogen storage bases should be used to benchmark the output stability and frequency adjustment capabilities of thermal power units to quantify the actual reliable capacity

to realize the dual-energy transmission of electricity and hydrogen and the large-scale energy supply with load following the source. Optimize the allocation of base capacity and analyze the significance of energy suppliers' participation in source-load bilateral investment in promoting the rapid transformation of the power system towards safe

efficient

green

and low-carbon goals.
