Cooperative planning strategy for distributed generation and sensitive users considering power quality

With the implementation of the strategy of constructing a new type of power system mainly based on new energy, the access volume of distributed generation (DG) and industrial users are growing rapidly. This paper proposes a cooperative planning strategy for DG and sensitive loads considering power quality to reduce the impact of voltage dip on DG and sensitive users. First, this paper analyzes the source-load resistance to voltage dip of the distribution network in a new type of power system with a large number of accessed DG and sensitive users. Secondly, a sensitive user siting model aiming at economy is established by considering voltage dip. Then, based on the improvement of the sensitive user siting model, the siting and capacity model of sensitive users and DG is established. Finally, in the IEEE30 node system model, the voltage dip data of the power system is obtained instead of the historical data using the fault point method, and the model planning is simulated and analyzed.
