Abstract

The demand for electricity has recently increased due to urbanization and the industrial revolution. In the beginning, electricity demand was mainly fulfilled by fossil fuel-based electricity generation, which today poses a great threat to the environment. Moreover, in the current scenario, the utilities of the power system are operating closer to the stability margin due to the huge load growth and unwanted power flow and it depends on the country, utility policy. energy efficiency, in order to solve this problem, energy production based on decentralized generation such as renewable energies, the static distribution compensators (DSTATCOM) in distribution networks has become of great interest and great importance because of their technical, economic and environmental impacts. This during the non-optimal integration of this production can lead to many problems and violations of operational limits, such as over voltages and under voltages, and increased active power losses. In this regard, this thesis presents an optimal integration procedure of distributed generation (DG) based on photovoltaic (PV) panels and DSTATCOM in a radial distribution network. The proposed procedure was formulated as a single-, and a multi-objective function, by using PSO, and firefly algorithms. The algorithms proposed in this thesis are used to determine the optimal size and location of DG and DSTATCOM, in order to improve the voltage profile and reduce active power losses in IEEE 33-JB and 69-standard distribution networks. JB. The results obtained confirm the effectiveness of the proposed algorithms to solve the problem of the optimal integration of DG and DSTATCOM.
