Special Issue Information

Dear Colleagues,

Machine learning in electrical drive renewable energy systems has been broadly implemented in forecasting of energy in power systems and various industrial applications. During the past few decades, there has been a vast increase in the development and implementation of different types of machine learning models in energy systems. Machine learning models are also broadly applied in power-electronic-based industrial drive systems. This includes speed and torque control of various dc and ac drives, feedback control of converter, tuning of offline P-I and P-I-D, nonlinearity compensation, online and offline computing, modeling, estimation of parameters, performance optimization of drive systems based on online finding, assessment for distorted waves, and many more. There is also a development in the accuracy, robustness, precision of the machine learning models in the energy systems by using various hybrid models.  Hybridization is found to be more beneficial for the development of estimation of various models, specifically for implementing various renewable energy technologies. Depending on the seasonal condition, machine learning has the capability to provide sensible and necessary assessment for a residence or building for power generation and it can report on when it will have to access the power from the grid. However, estimations of the demand of energy by implementing hybrid models using methods of machine learning have largely impacted the energy efficiency, controllability along with sustainability.

A control structure design of a three-phase three-leg four-wire grid-tied Distribution Static Synchronous Compensator (DSTATCOM) based on a combined-step-size real-coefficient improved proportionate affine projection sign algorithm (CSS-RIP-APSA) has been presented. The three-phase four-wire DSTATCOM is used for reactive power compensation along with harmonic current minimization. This strategy also helps in load balancing and neutral current compensation. The affine projection sign algorithm (APSA) is a member of the adaptive filter family, which has a slow convergence rate. The conventional adaptive filter deals with the trade-off between the convergence rate and the steady-state error. In the proposed algorithm, the RIP-APSA adaptive filter with two different step sizes has been designed to decrease the computational burden while achieving the advantages of a fast convergence rate and reduced steady-state error. The proposed controller also makes the inverter function a shunt compensator. The controller primarily evaluates the fundamental weight component of distorted load currents. The aim of the proposed system is to compensate for reactive power and to ensure unity power factor during the faulty conditions as well as for unbalancing grid conditions. The proposed control algorithm of the grid-tied DSTATCOM works effectively on the laboratory prototype as verified from the experimental results. Full article

Improving the efficiency of renewable energy and electricity utilization is an urgent problem for China under the objectives of carbon peaking and carbon neutralization. This paper proposes an optimization scheduling method of electric vehicles (EV) combined with wind and photovoltaic power based on the Frank-Copula-GlueCVaR. First, a joint output model based on copula theory was built to describe the correlation between wind and photovoltaic power output. Second, the Frank-Copula-GlueCVaR index was introduced in a novel way. Operators can now predetermine the future wind-photovoltaic joint output range based on this index and according to their risk preferences. Third, an optimal scheduling model aimed at reducing the group charging cost of EVs was proposed, thereby encouraging EV owners to participate in the demand response. Fourth, this paper: proposes the application of a Variant Roth–Serve algorithm; regards the EV group as a multi-intelligent group; and finds the Pareto optimal strategy of the EV group through continuous learning. Finally, case study results are shown to effectively absorb more renewable energy, reduce the consumption cost of the EV group, and suppress the load fluctuation of the whole EV group, which has a practical significance and theoretical value.
