Abstract

The main contribution to this project will be on the developments of techniques and models to assess the impact and coordinate the operation of distributed generation sources in the integrated volt-var control in distribution networks, aiming to explore the problem of energy efficiency through the voltage reduction, procedure called "Conservation voltage reduction" (CVR). This proposal will analyze the distributed generation technologies without variability in primary source and those that have a strong dependence on variations of the primary source (mainly wind turbines and photovoltaic systems) considering the technological capabilities of different types of converters coupling of distributed generator (DG) to the system. Regardless of the type of technology used, the impact it has connecting DGs in the distribution network can interfere with the objectives of the control voltage and reactive. For example, variations in the voltage levels associated with GD presence may interfere with the objectives of energy conservation programs, such as the CVR. Therefore, the connection of DGs in distribution systems necessarily requires proper coordination with other devices (On-Load tap changing OLTC, switched capacitor banks, voltage regulators, etc.) to guarantee the performance of the volt-var control. Therefore this study aims to develop a model and a methodology for the integrated volt-var control via multiobjective optimization for the operation of distribution networks with DG and thus able to investigate the effects of technical and economic benefits of the CVR and its relation to voltage quality. This approach should also indicate the magnitude of the actual costs and economic benefits of the optimized network operation. (AU)
