Future power system energy management for zero carbon emissions

According to the development trend of the power system, it can be predicted that the wind power, solar energy and some other kinds of renewable power generations will become more popular in the future. Therefore, this dissertation explores the impacts of the addition of renewable power generations on the operation of the power system. At the same time, since carbon neutrality and environmental protection have become a consensus of most countries in the world, the future power system will further move towards the goal of low carbon. So, the factor of carbon emission is also considered in this dissertation. Low-carbon penalty factor is added on the basis of the existing optimal power flow. The low-carbon penalty factor is a simplified idea which is set to change the generation price of different kinds of generators. 'Matpower' tool is used to simulate and compare the optimal solution of power system operation. By comparing the changes of operation status and generation cost of each unit before and after adding a certain proportion of renewable energy to a fixed 3-bus system, it can be concluded that renewable energy has some certain positive effect in the power system, which not only optimizes the system operation cost, but also limits the operation of high emission units, in order to reduce the overall carbon emission of the power system.Master of Science (Power Engineering
