The expansion and diversification of the Uruguayan energetic infrastructure, with significant penetration of renewable sources is leading to structural changes in the power system, in both transmission and distribution subsystems. These changes impact in the operation criteria and also in the power system protection.
This paper presents the simultaneous coordination for back to back control scheme using a B-spline artificial neural network. The main task is that the power converters operation adapt by itself during the grid changes. The basic problem consists of tuning the PI controllers simultaneously when the system and load are subjected to disturbances. The B-spline neural network is an efficient tool to implement...
This paper presents a survey of the impact of large-scale wind power plants on the identification of Voltage Control Areas (VCAs). A Monte-Carlo based framework is proposed for the probabilistic analysis of variations in the arrangement of the VCAs, the critical buses as well as of estimation of the statistical properties of the loading margin. Test results, performed on the IEEE 39-bus system, showed...
The design of a passivity-based non-linear controller for a shunt active filter to be used for the compensation of the harmonic components consumed by non linear loads is presented in this paper. The main objective of this control strategy is to inject the necessary compensation current into the system so that the grid current is sinusoidal and balanced, regardless of whether the grid voltage is unbalanced...
The positive impact of solar generation in the current power systems is growing rapidly due to energy increasing demands, depletion of fossil fuel sources and the environmental requirements of pollution reduction. Maximum Power Point Tracking (MPPT) methods are integrated with Photo Voltaic (PV) systems in order to maximise the energy obtained under every weather conditions and deal with the associated...
