This paper aims to present a centralized adaptive protection scheme (APS) for the directional overcurrent relays (DOCRs) considering system dynamics such as load demand variations, topology changes and DGs to mitigate the above-mentioned effects. The scheme is suitable for different types of networks whether its radial or meshed. Afterall, it can determine the actual topology with the micro-PMUs and breaker status, automatically generate relay names accordingly with the topology bus locations, establish protection coordination pairs, coordinate DOCRs for parallel lines, identify transformers to offer backup operation for differential protection, perform load flow and fault studies, execute contingency and sensitivity analysis, and lastly, coordinate the DOCRs using differential evolution algorithm so that they always have the proper settings to operate in appropriate time providing selectivity. The performance of the proposed centralized adaptive overcurrent protection scheme is tested on the highly meshed IEEE 14 bus system. The proposed scheme has shown that it can adequately consider impacts of system dynamics and DG.

The park’s electric refrigeration system exhibits complex coupling relationships and heterogeneous operational characteristics, making it difficult to achieve optimal operation. Therefore, a strategy for optimizing the park’s electric refrigeration system, considering the potential for mutual assistance from multiple energy sources, is proposed. Firstly, an introduction to the structure of the park’s electric refrigeration system is provided. Subsequently, operational constraints for the park’s units are established through quantitative analysis of the operational characteristics of systems such as the photovoltaic power generation system. Based on this, an optimization scheduling strategy for the park’s electric refrigeration system is proposed to minimize system operating costs. Finally, the model is transformed into a Mixed Integer Linear Programming (MILP) problem by employing linearization techniques. Simulation results demonstrate the effectiveness of the proposed strategy.

“…Economic load dispatch (ELD), a subset of the unit commitment issue, is a signifcant problem that deals with minimizing the operating cost of a power production facility, with power system engineers' primary duty being to examine the economics of power systems [4,[10][11][12]. Economic dispatch additionally aids throughout the reduction of global pollutants and fuel usages [13][14][15][16][17]. Furthermore, it is essential to address the ELD problems concerning the constraints to avoid unwanted mishaps such as power system breakdowns and also to enhance the security of an electric system [18][19][20][21].…”

Hybrid generating systems in power networks have emerged as a result of the rapid growth of renewable infrastructure and widespread support for green energy. One of the most significant problems in designing and operating an electric power generation system is the efficient scheduling of all power generation facilities to meet the rising power demand. Economic load dispatch (ELD) is a generic procedure in the electrical power system, and the ELD in power system problems involves scheduling the power generating units to reduce cost and satisfy system constraints. Metaheuristic algorithms are gaining popularity for solving constrained ELD issues because of their larger global solution capacity, flexibility, and derivative-free construction. In this research, the ELD problem of integrated renewable resources is solved using a unique solution model based on hybrid optimization. Furthermore, this work considers multiobjectives such as total wind generation cost, total cost function of thermal units, and penalty cost function. The hybrid optimization model optimizes the power generation of thermal power plants within the maximum and minimum limitations. Additionally, the turbines are selected optimally by the hybrid optimization model to ensure the power generation of wind turbines based on the demands. The proposed hybrid optimization is a combination of particle swarm optimization (PSO) and cat swarm optimization (CSO), and the new algorithm is referred to as the particle oriented cat swarm optimization model (POCSO). Finally, the performance of the proposed work is compared to other conventional models. In particular, the cost function of POCSO is 6.25%, 6%, 11.7%, 36%, 27%, and 46.42% better than the cost function of whale optimization algorithm (WOA), elephant herd optimization (EHO), moth-flame optimization (MFO), dragonfly algorithm (DA), sealion optimization (SLnO), CSO, and PSO methods, respectively. Also, for IEEE-30 bus system, the best value of the proposed work is 7.46%, 5.41%, 16.30%, 14.88%, 17.60%, 13.86%, 15.21%, 17.49%, and 4.27% better than that of the PSO, CSO, SLnO, DA, MFO, EHO, WOA, multiagent glowworm swarm optimization (MAGSO), and Harris hawks optimization-based feed-forward neural network (HHO-FNN) methods, respectively.
