Impact of PV Compensation in Improving the Voltage Drop in Electrical Networks LV

Abstract

Photovoltaic systems connected to a network are increasingly used in developed countries. These systems are installed at the prospect of developing this type of clean energy without the emission of pollutant gases.The availability of energy is an important factor for the development and improvement of living conditions of the population. The availability at all times and the quality of this energy are highly demanded. Thus, the quality of the voltage measured by the voltage drop becomes unacceptable when it exceeds 10%. The distributor makes various techniques such as: strengthening of sections of the conductors, installation of new stations MV/LV transformers, etc. .Knowing that the voltage quality is affected by the distance between the power source and load. The installation of PV systems connected to the grid, in underserved areas, is a solution increasingly used to solve the problem of voltage drop and for the same opportunity to provide clean electricity.Support tools to determine the profitability and performance of PV systems connected to the LV network have been used. Thus a real case study was performed on a rural network LV, headquarters operating constraints. The network studied is located north of Algeria in the rural town of Mouafkia, wilaya of Chlef.The connection instead of the voltage drop to a mini-solar power plant, improves the electrical quality of the line by injecting into the network of clean electrical energy photovoltaic own to benefit the rural population.The calculation results obtained with the software JPlec showed that using solar photovoltaic injected into the LV, a significant portion of non-polluting electrical energy can be produced.Thus, it allows the customer to rectify the voltage during periods of high demand, the afternoon of the summer season, and occasionally reduce the purchase of electricity from the grid.
