It is known that reactivepoweroptimisation is of great significance to improve the electrical power quality. How the security, reliability, and economy of the system can be effectively improved by reactivepoweroptimisation has attracted the attention of scholars. In this study, according to the characteristics of an isolated grid of the new energy clusters connected to voltage source converter-based high-voltage direct current, the multi-objective reactivepoweroptimisation model, which takes the network loss, and the reactivepower margin of new energy clusters into consideration, is established. In particular, the maximisation of reactivepower margin of new energy clusters is chosen as one goal, thus the response speed of voltage control can be effectively improved, and the preventive control of transient voltage stability of new energy clusters will be realised. Afterwards, using the weighted method the multi-objective optimisation model can be transformed into a single-objective optimisation model and the particle swarm algorithm is utilised to obtain the optimal solution. Finally, the simulation results show that the reactivepoweroptimisationapproach proposed can effectively reduce the network loss of the system, increase the reactivepower margin of the new energy clusters, and improve the quality of the system voltage.
