What is the ANN-PSO algorithm and how can it be used to improve the efficiency of a vehicle-to-grid system?3 answersThe ANN-PSO algorithm is a hybrid algorithm that combines Artificial Neural Networks (ANN) and Particle Swarm Optimization (PSO). It can be used to improve the efficiency of a vehicle-to-grid system by optimizing the control strategy parameters and achieving better global optimization results. The algorithm is able to overcome the problems of poor local optimization ability and premature convergence, which are common in traditional PSO algorithms. By using the ANN-PSO algorithm, the firing angles of thyristor-controlled reactors (TCR) can be controlled to vary the amount of reactive power at the load side, thus mitigating voltage unbalance in electrical power systems (EPSs). Additionally, the algorithm can be used to model an orderly charging strategy for electric vehicles (EVs), reducing the impact of disorderly charging on the grid and improving the user's satisfaction.
