Adequate Operation of Hybrid AC/MT-HVDC Power Systems Using an Improved Multi- Objective Marine Predators Optimizer

This paper presents an Improved Multi-Objective Marine Predators Optimizer (IMMPO) for optimal operation of hybrid AC and multi-terminal-high voltage direct current (AC/MT-HVDC) power systems. The proposed IMMPO incorporates external repository to conserve the non-dominated preys. Furthermore, fuzzy decision making is employed select best compromise operating point AC/HVDC In these systems, active reactive controllability source converters (VSCs) are activated besides full control in grids via committed generators, transformer tap settings VAR compensations. modelling VSC losses integrated its quadratic function converter current. AC/MT-HVDC systems handled as a multi-objective problem minimizing total fuel costs, environmental emissions generation units over AC, HVDC transmission lines VSCs stations. For solving this problem, several recent optimization algorithms applied on modified standard IEEE 30-bus. Also, real part Egyptian West Delta Region Power Network emerged with VSC-HVDC considered practical case study. simulation results demonstrate effectiveness preponderance algorithm great stability indices competitive algorithms. Nevertheless, successfully extracting well-diversified Pareto solutions while effectively produced satisfy operator requirements.
