In order to enhance the wind power consumption rate

achieve the goal of energy and power carbon peak and carbon neutral

with the goal of the lowest comprehensive cost of the power system

a new energy power system low carbon economic optimization method is proposed to establish the source and load side of the planning model. Firstly

on the source side of thermal power units

low-carbon transformation is performed

and a solution memory and flue gas bypass system is set up to make the unit become a liquid storage carbon capture unit

and dispatchable resources of photovoltaic power plant(concentrating solar power

CSP) and storage battery is introduced to coordinated with wind power. Then

on the load side

the price and incentive-type demand response resources are used for peak shaving and valley filling

and adjusting the users' power consumption behaviors and power consumption. Finally

four cases are verified

and the results show that

the decarbonization of the power system from both the source and load sides can help promote wind power consumption

increase the share of renewable energy generation

enhance the low-carbon performance of the system

and save costs.
