Background:
The improvement of the voltage in power lines and the respect of the low voltage
distribution transformer substations constraints (Transformer utilization rate and Voltage drop) are
possible by several means: reinforcement of conductor sections, installation of new MV / LV substations
(Medium Voltage (MV), Low Voltage (LV)), etc.
Methods:
Connection of mini-photovoltaic systems (PV) to the network, or to consumers in underserved
areas, is a well-adopted solution to solve the problem of voltage drop and lighten the substation
transformer, and at the same time provide clean electrical energy. PV systems can therefore contribute
to this solution since they produce energy at the deficit site.
Results:
This paper presents the improvement of transformer substation constraints, supplying an end of
low voltage electrical line, by inserting photovoltaic systems at underserved subscribers.
Conclusion:
This study is applied to a typical load pattern, specified to the consumers region.
