Contribution à l'analyse de la stabilité transitoire des réseaux électriques en présence des sources renouvelables et des dispositifs de stockage en présence des éléments facts par les méthodes méthaheuristiques : application au réseau Algérien

Abstract

The transient stability improvement in power systems leads us to a good security of power subjected the most serious faults in the electrical networks. Among the elements that can increase the transient safety rate studied are the presence of excitation system integrated into synchronous machines called generators, conventional compensators absorbers/or producers of reactive energy injected in the bus to adjust the level of the sufficient voltage and thus the integration of FACTS compensators such as (SVC, and STATCOM) play an important role for transient stability improvement. Nonlinear methods are used to solve the fault problems. Investment in renewable energies is necessary to increase the production rate and reduce the cost function of thermal-based power plants using the method of power flow optimizations (IP-OPF) in the presence of transient constraints, and a meta -heuristics method. (PSO) is used to minimize the active loss in electrical networks. Including the constraints of compensators systems, transformers taps, and voltages buses that generators are recorded. The networks applied in this thesis are: infinite bus network, IEEE30 and NEW ENGLAND network, South East Algerian network, Algerian 114Bs network. The obtained results are confirmed to our objectifs.
