Under the change of global energy structure and low carbon economy development, power system has to achieve from high-carbon to low-carbon basic transformation. In the whole power system, as the core of the power system, it is very important to measure and manage accurately carbon emissions on PGSs(GAO Hong et al., 2011; GAO Hong et al.,2012), of which effects are significant in promoting low-carbon transformation. A Dynamic Carbon Emission Measurement Model (DCEMM) of the PGS is built on the basis of carbon emission flow theory, which is able to measure the carbon emission during power grid operation timely and accurately, and is applied to low-carbon dispatching and demand response for power system. By the case, the precision and reliability of such model are verified, in which not only the total carbon emission of those optimized power system is reduced apparently and economy operation cost is lowered too so that itself energy structure has been changed into a cleaner and efficient direction, but also more stable and efficiency running state can be maintained for power grid. The research results show that the DCEMM on the grid side has obvious real-time, accuracy and wide applicability, which provides a scientific basis for the optimal dispatching of power system, helps operators to formulate more environmentally friendly and economical operation strategies, and promotes the low-carbon transformation and sustainable development of power system.
