“…Using the charge and flux balance principles presented in 7and 8, expression (23) is rewritten as constraint (24), which defines the relation between the minimum derivative of i dc and the parameter k i that ensures the existence of the sliding mode. In this expression, the term (−d) is negative, and the term k b…”

“…The charger/discharger converter is controlled to regulate the DC bus voltage within safe limits and simultaneously impose a given energy flow between the battery and the DC bus. Due to safety implications for the source and load, there are many research papers focused on regulating the DC bus voltage using charger/discharger converters: some of them are based on linear control [16,[23][24][25][26], others are based on intelligent control [13,[27][28][29][30][31][32], and others are based on non-linear control strategies [15,[17][18][19][20][21][22]. In particular, sliding-mode controllers (SMCs) have been widely used for this application to ensure global stability, robustness to parameter tolerances, higher bandwidth compared with classical linear controllers [17,22,33], and reduced implementation cost and complexity compared with intelligent controllers [31,34].…”

Stand-alone power systems based on renewable energy sources are widely used for energy generation in remote locations and for distributed generation in urban environments. The DC bus is an essential component of these systems since it enables power transmission between the sources, loads and batteries. The batteries are interfaced with the bus using a charger/discharger DC/DC converter, which is controlled to regulate the DC bus voltage under any operating conditions. This is an important task because unsafe over-voltages and under-voltages in the bus could damage the sources, loads and power converters. This paper proposes a sliding-mode controller for a charger/discharger DC/DC converter with improved disturbance rejection to provide a tight bus voltage regulation for safe operation. The main novelty of this solution is the inclusion of the bus current in the sliding surface, which accelerates the controller response. Moreover, a formal proof of the system global stability is provided, and a detailed process is developed to calculate the controller and implementation parameters. Finally, the proposed solution is validated through simulations and experiments.

“…The authors also explain how the hybrid system is eco-friendly with the environment compared to the conventional power plant. The integration of standalone hybrid energy system is most economical and fuel-saving with maximum utilization of full load capacity of 80-100% [99]. The off-grid hybrid system with different battery technologies using genetic algorithm is discussed to achieve the system reliability [100].…”

The power consumption has increased enormously due to the intervention of high end technology and it is necessary to meet this power demand. The power pushed into any electrical system should be highly reliable, secured with sufficient quantity and quality. One such solution is to bring reliable and flexible power by introducing Hybrid energy systems into the network. The main motivation of hybrid energy systems is to improve the delivery of power at the utilities and customer end. In this paper, a complete literature review is made on the integration of solar photovoltaic, wind and diesel generator with energy storage systems like hydrogen based fuel cells and batteries. This hybrid system reduces the operating time of diesel generator, save the fuel consumption and hence accomplishes the peak demand with diesel generator.

“…In PV energy conversion and distribution systems, three-phase four-leg inverters are becoming popular in specific applications such as standalone [1] and Uninterruptible power supply (UPS) systems [2], as well as in islanded mode when the grid supply has failed [3]. A standalone PV system has to provide uninterrupted and balanced/unbalanced power for utilities such as data communication, aircraft, home appliances, satellite stations, and railway systems [4].…”

Near State Vector Selection-Based Model Predictive Control with Common Mode Voltage Mitigation for a Three-Phase Four-Leg Inverter

et al. 2017

Abstract:A high computational burden is required in conventional model predictive control, as all of the voltage vectors of a power inverter are used to predict the future behavior of the system. Apart from that, the common mode voltage (CMV) of a three-phase four-leg inverter utilizes up to half of the DC-link voltage due to the use of all of the available voltage vectors. Thus, this paper proposes a near state vector selection-based model predictive control (NSV-MPC) scheme to mitigate the CMV and reduce computational burden. In the proposed technique, only six active voltage vectors are used in the predictive model, and the vectors are selected based on the position of the future reference vector. In every sampling period, the position of the reference current is used to detect the voltage vectors surrounding the reference voltage vector. Besides the six active vectors, one of the zero vectors is also used. The proposed technique is compared with the conventional control scheme in terms of execution time, CMV variation, and load current ripple in both simulation and an experimental setup. The LabVIEW Field programmable gate array rapid prototyping controller is used to validate the proposed control scheme experimentally, and demonstrate that the CMV can be bounded within one-fourth of the DC-link voltage.Keywords: near state vector selection based model predictive control; common mode voltage; ripple content; execution time; computational burden and three phase four leg inverter
