Optimal Intelligent Energy Management to Integrate a Photovoltaic Park into Electricity Grid Using a Real-Time Objective Function—Application to the Naâma Park

In order to improve the performance and solve the problem of integration of renewable electrical powers from a photovoltaic park at the peak time, optimal production management as well as synchronization with the increase in normal consumption, not only solve the droop voltage but also minimizes the cost of producing electricity from natural gas. Using software designed and developed, the load curve for a duration of 16 h gives the objective function the set point to find the improved voltage solution and the optimal location for reactive compensation in a real electrical network. This planned solution supports the sustainable development on the radial network 225 kV of Saida-Bechar region, and increases the stability margin for the five substations positions to study in N and N-1 situations. Analysis techniques, modeling and control system are studied and confirmed by exploiting the advanced numerical simulation. In this contribution, we studied the voltage drop in remote stations due to the high electrical load, we have solved the problem of voltage drop by local reactive compensation and the use of active power from photovoltaic farms in order to relieve and reduce the production costs of the gas turbine in bus 15. Finally, a reduction of 19.23% in the total active losses of the electrical system and an optimal location of the bank of capacitors from 5 Mvar to bus 12.
