In this study, symmetrical component-based current injection is used to analyse a single-stage grid-connected inverter with low voltage ride-through (LVRT) capability. During voltage sags, the renewable source-fed voltage source inverter (VSI) may disconnect from the main grid at the point of common coupling. This condition arises due to the Under-voltage/over-current protection in the renewable inverters. This sudden dis-connecting of the inverters may cause voltage collapse, frequency instability, and synchronous angle instability in utility networks with significant penetration of power from renewable inverters, which can result in blackouts. Utility grid rules require low-voltage ride-through capabilities in grid-connected inverters to mitigate this effect. In order to support voltage and reduce volt-age imbalance at the point of common coupling, a symmetrical component-based real and reactive power injection approach has been developed in this study. This technique is implemented by considering the constraint of not exceeding the inverter's rated current capability. The proposed technique effectively boosted the positive sequence voltage component to a reference value by using a PI controller. The negative sequence reactive power was drawn using the remaining reactive power capacity in order to suppress the voltage's negative sequence component. Results are presented in the paper for various voltage sag conditions. The proposed techniques are validated by simulating the model in a Matlab simulink environment.

This paper highlights the demand response (DR) approach as a useful strategy to improve frequency management in a contract violation scenario involving a restructured power network. The analysis is carried out in the DR framework with the integration of the thermal plant, the biogas unit, the solar thermal trough (PTST), and the wind farms. However, an electric vehicle (EV) application is utilized that jointly meets some of the uncontracted demand. A thorough examination of the test system that uses the DR technique greatly enhances the frequency regulation services, which provide a significant improvement over conventional frequency regulation in terms of system dynamics. Sensitivity analysis with a ± 25% variation in system parameters is also taken into account while analyzing system dynamic behavior using the DR framework.

Many countries in their grid codes have assigned the grid frequency control function to the photovoltaic (PV) systems to handle the ever increasing of PV systems integration into power grid. In order to have power reserve for providing the upward frequency regulation in the case of falling grid frequency, these PV systems are operated at an active power less than the maximum available power according to these grid codes. Previously published power reserve control strategies are either very complex to implement or they have used the expensive solar irradiation and temperature sensors. Hence this paper has proposed a novel power reserve control strategy which is very easy to implement and do not require expensive solar irradiation and temperature sensors. Performance of the proposed power reserve control strategy is verified for the change in the power reserve command using MATLAB/SIMULINK simulation results.

Unified Power Quality Conditioners are used frequently in modern distribution networks to eliminate power quality issues. Furthermore, compared to other existing power quality enhancement devices, UPQCs can concurrently improve both voltage and current profiles. To enhance their power quality issue compensation capability, multilevel inverters can replace the traditional two-level inverters in UPQCs. This study aims to investigate the behavior of diode-clamped multilevel inverters based UPQC when integrated with a Photovoltaic system in the presence of non-linear loads. Finally, a MATLAB/Simulink simulation was conducted to observe the performance of the proposed UPQC configuration by utilizing synchronous reference frame (SRF) and hysteresis control methods. The simulation results when obtained from both control strategies were compared to identify which method can improve the operating capability of the proposed UPQC configuration.

This paper presents the design and the development of $boldsymbol{100}mathbf{W}$ solar power systems for a scientific buoy known as Ocean Data Acquisition System (ODAS) Buoy. There are two separate solar power systems proposed in this paper; one for the buoy and the other one for a ground station. The characteristics of solar data, type of PV modules, total load demand, battery sizing, and converter and inverter ratings are major factors that need to be considered in designing and developing the standalone PV systems. The results have shown that this method has provided reliable and sufficient battery storage to power all the loads continuously without any interruption.

The increasing demand for electric power and heightened environmental protection awareness have rapidly grown distributed generation (DG) in recent years. Consequently, this research aims to investigate the optimal location and capacity for DG based on multiple objectives, such as the minimization of active power losses, the improvement of the voltage profile, and the cost reduction of the network. To this end, an algorithm inspired by the behavior of lion ants, known as the Ant Lion Optimizer (ALO), has been proposed as a possible solution. The ALO algorithm is a nature-inspired meta-heuristic that can provide near-optimal solutions for complex real-world optimization problems. Thus, the ALO algorithm is expected to provide solutions close to optimal while being computationally efficient.

Virtual oscillator control (VOC) is a very popular method for the control of parallel inverters. In this work, Deadzone oscillator (DZO) based VOC and Hopf oscillator (HO) based VOC is presented to regulate the parallel inverters in a standalone microgrid (MG). The voltage amplitude and frequency reference of the inverters are coming from the oscillator dynamics. The extensive comparison of DZO and HO based control methods with different types of loads is also presented in this work. The HO based control method minimizes harmonic distortion and achieves faster time response compared to DZO based control method. The simulation results show the efficacy of the HO based control method.

The increasing cost of electricity generation using fossil fuels has increased the growth in renewable energy resources (RER). In the context of commercial buildings., the electricity bill comprises energy usage in kWh and peak demand in kW. To reduce peak demand and thus electricity costs., a hybrid solar photovoltaic (PV) and battery energy storage system (BES) can be used to replace grid energy requirements. Yet., despite their attractiveness., PV and BES introduce another dimension of complexity. Therefore., careful selection of PV and BES capacity based on load demand is required to reduce total investment costs and the monthly electricity bill without sacrificing reliability. The PV -BES system is developed for a 20-year operating period using a single-objective optimization approach to reduce the objective function., which is the total net present cost (NPC). In this paper., a PV -BES energy management system with peak shaving is designed using real-time load patterns., solar insolation., ambient temperature., Malaysian net energy metering (NEM)., and the limitation of maximum exporting power supplied to the grid. Based on a scenario where PV capacity is constrained by the availability of rooftop space and NEM rates., the optimal PV and BES capacities are obtained for the analyzed system. The case study demonstrates that the average monthly cost of electricity bills could be reduced by 22.27%. It also revealed that the annual energy consumption and peak demand could be reduced by 22.62% and 15.85%., respectively., with additional benefits by selling 6177.782 kWh of electricity to the grid. The proposed method could be useful for sizing the PV-BES system for any Malaysian commercial building.

Resonant Inductive Power Transmission (RIPT), a wireless power transfer technology, is a cutting-edge option for Electric Vehicle (EV) battery charging systems. RIPT is a safe and practical method of charging electric cars (EVs). RIPT systems must have high-power transmission, dependability, robustness, and cost in order to achieve highway charging. This study illustrates a multi-legged dynamic wireless charging system wherein each leg of the inverter is utilized separately for every transmitter coil to bring down the system cost. Each space between two transmitters coils a sensor attached to the road pavement that serves as a trigger when a receiver coil passes over a path used for charging. This work's transmitter part includes a proposal for a multi-leg converter. To drive a transmitter coil, each leg of the converter acts as a half-bridge high frequency inverter circuit. The proposed system achieved 76% in experimental analysis.
