Active control system of the energy in low voltage distribution networks

This paper presents the development and results obtained from an active control system of the energy in low-voltage networks subjected to disturbances, and in which the maintenance of the anticipated voltage margins is an important factor. This system, due to its good performance in a dynamic regime, is a rapid voltage stabiliser that insulates the network from disturbances caused by nonlinear charges, allows for reactive energy and harmonic control, and de-sensitises the load during short-term voltage sags. At the same time, it permits the automatic programming of the output voltage value in order to save energy.
