Utilization of renewable energies in association with energy storage is increased in different applications such as electrical vehicles (EVs), electric boats (EBs), and smart grids. A robust controller strategy plays a significant role to optimally utilize the energy resources available in a power system. In this paper, a suitable controller for the energy resources of an EB which consists of a 5 kW solar power plant, 5 kW fuel cell, and 2 kW battery package is designed based on the linear parameter varying (LPV) controller design approach. Initially, all component dynamics are augmented, and by exploiting the sector-nonlinearity approach, the LPV representation is derived. Then, the LPV control method determines the suitable gains of the states’ feedbacks to provide the required pulse commands of the boost converters of the energy resources to regulate the DC-link voltage and supply the power of EB loads. Comparing with the state-of-the-art nonlinear control methods, the developed control approach assures the stability of the overall system, as it considers all component dynamics in the design procedure. The real-time simulation results demonstrate the performance of the designed controller in the creation of a constant DC-link voltage.

“…Hence, both current values are very close to each other in steady-state when using the average model, and noticeable effect of parameter variation can be seen during dynamics only. As mentioned, a change in performance can be detected and identified with an observer (estimator), [13][14][15][16][17][18][19][20][21][22]. Due to ageing or a change in parameters due to accidents (after-shock variation), a slow change in dynamic performance occurs.…”

This paper presents the design, analysis, and evaluation of a method for detection of the performance degradation due to component ageing, after-shock change in parameters, or excess in environmental conditions. The major novelty of this method consists of using a statistical based decision process rather than one-off threshold-based switch for detection of deterioration in performance. The method builds upon the previous observer-based method for abrupt (catastrophic) fault detection, and uses a Cumulative Sum algorithm for detection of slow trends in performance. Firstly, a review outlines the rates of change in various parameters due to ageing of components. The design and a comprehensive analysis of the proposed method are performed offline in MATLAB® using an average State Space model. Contrary to previously expensive observer-based methods, the implementation is proposed on a low-cost microcontroller, and demonstrated at a 142 kHz sampling and switching rate. Timing diagrams and resources for implementation are also discussed.

Fuel and solar cells are broadly used in Microgrids. However, their output varies widely when load and environment change extensively. Thus, DC‐DC converters are used for wide‐range voltage application. Nevertheless, output filter inductor is large and voltage stress of diodes is high in two‐level converters when input voltage varies widely. Therefore, a T‐type three‐level converter is proposed. A T‐type cell is added into the full‐bridge (FB) converter. The proposed converter can work in two‐ and three‐level modes, that is, 2L and 3L modes. It works in 2L mode in high input voltage. Thus, the output filter inductance and voltage stress of diodes in 2L mode decrease compared to the FB converter. Operating principle is illustrated. In addition, design guidelines and examples are shown. Finally, experimental results confirm the theoretical analysis.
