Item PMU optimal placement in wide area monitoring systems using grey wolf optimization technique(2019) Azzougui, Yasmina; Recioui, Abdelmadjid; Mansouri, A.Wide area monitoring system requires the integration of an advanced technology that provides real time synchronized phase angle measurements at all their measurement points. The phasor measurement units are the most advanced devices to achieve that. The objective of this work is first, to find the optimal placement of a minimum number of PMUs in some standardized IEEE systems. Next, the same method was applied to the Algerian 63 bus system. Two cases are taken into consideration: the minimum number of PMUs without considering the ZIB, then, considering the ZIB. The simulations are carried out using MATLAB/SIMULINKItem Hardware and software load power control in smart home applications based on Taguchi optimisation technique(Inderscience, 2018) Azzougui, Yasmina; Recioui, AbdelmadjidPower control is one of the concerns in smart grid implementation. The balance between the supplied power and the demand must be maintained so that blackouts are avoided. Smart metres play an important role in establishing this balance. On the other hand, power control implementation is a challenge as one would have to find the right mix between the hardware and the software parts. The purpose of this work is to optimise and implement a small power control system of home appliances. The objective of the optimisation is to reschedule some tasks if the power demand exceeds a certain peak level. The optimisation is based on Taguchi method which is known of its robustness and relatively fast convergence. The system casts a real life situation and can be considered as a small-scale prototype that can be extended to larger systemsItem Application of the moth flame optimisation to the selective harmonic elimination in multilevel converters(Inderscience, 2018) Azzougui, Yasmina; Recioui, AbdelmadjidHarmonics constitute one of the power quality headaches that need to be dealt with seriously in the modern power grids. Particularly, the integration of renewable energy systems has brought with it more harmonic pollution due to the need of power electronic switching devices. In this work, it is attempted to employ one of the proliferating optimisation techniques to solve the selective harmonic elimination problem in conjunction with a reduction of the overall system total harmonic distortion (THD). The moth flame optimisation technique is found very capable of handling such a problem and the results demonstrate the effectiveness of the method and the applicability of the designed switching system
