Life-Cycle Low Carbon Simulation of Smart Distribution Network Considering Power Loss

摘要

In order to cope with today's climate change and energy crisis, green and low-carbon is an inevitable trend in the electric power development in the future. Smart distribution network is one of the important means in reducing carbon emission of the power system. The research on the relationship of the carbon emission in different stages of the life-cycle of smart distribution network is significant for the green environment-friendly and low-carbon development of the power system, as also the research of the methods to reduce carbon emission. Currently, most of the calculation theories of carbon emission are based on the lossless network, but the practical power system is lossy, so it is necessary to study the calculation method of the carbon emission flow in the full life-cycle of smart distribution network with the consideration of power loss. In the background of low-carbon power system, this paper analyzes the influence of distributed generators (DGs), energy storage systems (ESS), EV chargers on carbon emission of smart distribution network. Considering the access of DGs, ESS and EV chargers on smart distribution network, a life-cycle theory of carbon emission flow is proposed. Suggestions for the low-carbon operation mode of smart distribution network is proposed. The IEEE 33-node distribution system is used to validate the feasibility of the method. An example of a practical smart distribution network in Shanghai is taken at the end.
