Research on Distributed Generation Access to Distribution Network for Siting and Capacity Determination and Reactive Power Optimization

In order to carry out the optimal allocation of distributed generation in the distribution network, this paper proposes a single-objective particle swarm optimization algorithm combining improved inertia weights and small habitat technology, constructs a multi-objective function of weights in terms of network loss and voltage quality, applies the Newton-Raphson method of current calculation, carries out a siting and capacitance determination and reactive power optimization study on the integration of distributed power in the distribution network, and verifies it through the simulation on the IEEE33 node system, which shows that both network loss and voltage quality can be raised and reduced significantly. The results show that the voltage quality lifting and network loss reduction have obvious effects.
