An increasing adoption of rooftop photovoltaic (PV) generators presents a growing opportunity for the use of their grid-tie inverters to provide reactive power compensation on medium- and low-voltage distribution networks. This paper presents a generalized method based on particle swarm optimization (PSO) for determining how much reactive power is necessary to provide control over the voltage profile...
In spite of ABC theory was developed in parallel with pq theory, the second has been more widely used for reactive power compensation due to its flexibility. Indeed, conventional ABC theory is simple and efficient for balanced voltage sources but induces undesired zero sequence currents whether the voltage source is unbalanced. In addition, only one compensation objective is achieved. This paper presents...
For a long time, the research about the impacts of reactive power compensation devices on reactive power margin and voltage stability in power system has been important. Under the electrical market environment, the reactive power margin computation becomes even more necessary. By adopting the idea of heuristic energy function, this paper formed the energy models of two-bus and multi-bus system. Based...
