Optimal Configuration of Distributed Generation Considering Carbon Trading and Reactive Power Compensation

Abstract

Under the background of “double carbon”, the introduction of carbon trading and reactive power compensation mechanism in the planning of distributed generation is an important means to realize the low-carbon and stability of power system. Therefore, a optimal configuration method of distributed generation considering carbon trading and reactive power compensation was proposed. Firstly, the carbon trading mechanism was introduced to establish the calculation model of carbon trading cost. Then, a two-tier optimal configuration model of distributed generation considering carbon trading and reactive power compensation was established. The upper layer took the annual comprehensive cost as the optimization objective, and the decision variables were the location and capacity of photovoltaic and gas turbine connected to the distribution network. The lower layer took the system network loss, voltage offset and node voltage stability as the optimization objectives. The decision variables were the location and capacity of the reactive power compensation capacitor in the distribution network. Finally, the optimal configuration model was solved by the improved adaptive genetic algorithm. Combined with the example of IEEE33 node structure, the simulation analysis was carried out. The results show that the model can effectively reduce the loss of network and improve the stability of system voltage on the basis of ensuring the economy and environmental protection of the system.
