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.

Combined with the actual situation of transformer substation, PSO model is built to optimize the shunt capacitor series reactance rate in this paper. First, system harmonic impedance is analyzed and the harmonic impedance model is built. Second, the objective function and constraints of the optimization algorithm were set. The goal is to make the current distortion rate of high side smallest under the condition of the capacitor banks working safely, the output results will be the optimal allocation of the series reactance rate. Current-limiting reactor was also considered the influence to the design of series reactance rate. At last, testify the effectiveness with comparing the effect to the traditional way of designing the series reactance rate and prove the significant influence of the current-limiting reactor.

The authors provide a method for compensation of the reactive power inside a well. In the environment Matlab/ Simylink a model was developed of the site of the electrical centrifugal pump unit power supply from the transformer substation. A comparison is made of the proposed method of downhole reactive power compensation with the existing method.
