This paper presents a novel image-based path planning algorithm that was developed using computer vision techniques, as well as its comparative analysis with well-known deterministic and probabilistic algorithms, namely A* and Probabilistic Road Map algorithm (PRM). The terrain depth has a significant impact on the calculated path safety. The craters and hills on the surface cannot be distinguished in a two-dimensional image. The proposed method uses a disparity map of the terrain that is generated by using a UAV. Several computer vision techniques, including edge, line and corner detection methods, as well as the stereo depth reconstruction technique, are applied to the captured images and the found disparity map is used to define candidate way-points of the trajectory. The initial and desired points are detected automatically using ArUco marker pose estimation and circle detection techniques. After presenting the mathematical model and vision techniques, the developed algorithm is compared with well-known algorithms on different virtual scenes created in the V-REP simulation program and a physical setup created in a laboratory environment. Results are promising and demonstrate effectiveness of the proposed algorithm.

Distributed generation and energy storage technologies have helped SmartGrid projects gain great momentum over the last decade. However, despite a large number of pilot and demonstration projects, low-level information is often unavailable. Therefore, tools for defining and building different operation scenarios are required. These tools can facilitate adopting novel approaches to multi-domain energy management. This paper proposes a distributed, flexible co-simulation framework to integrate simulators from separate domains and platforms. Particularly, the proposed scheme enables the development of hybrid thermal-electric systems for smart buildings. In this study, an object-oriented approach to modeling electrical thermal storage (ETS) units is also suggested. The evaluation process is carried out using real-world data. A case study is practiced by designing a residential agent that performs model predictive control (MPC) of residential heating load in the presence of ETS. The results show that proper integration of ETS into Home Energy Management Systems (HEMSs) can achieve economic savings of up to 45 %. The findings of this study demonstrate ETS’s high potential for reducing customer bills while satisfying users’ comfort. Furthermore, they recommend practical strategies for short-term planning of smart grids by increasing their flexibility based on ETS-integrated Demand Response (DR) programs.

Bipolar DC grids are gaining great attention in modern power systems due to their superiority over Unipolar DC grids and AC grids. Existing studies on DC microgrid operations and controls individually investigate voltage control and balancing, power-sharing, and fault-tolerant operation. However, simultaneous investigation of voltage control, balancing, fault-tolerant operation and maximizing intermittence renewable energy in bipolar dc grids is important to understand the overall system behaviour. This paper presents a grid-connected bipolar DC microgrid architecture and control strategies to maximize the intermittence renewable energy usage, and reliable operation under fault conditions. The proposed DC microgrid can ensure reliable operation under healthy and faults conditions while utilising a high percentage of renewable energy, being verified through numerical results.

For space rockets, a rotating mixer is used to produce solid fuel. However, mixing with the rotary mixer is subject to high shear forces that limit the equipment drive. In a previous study, the authors developed a new production method using a pneumatically driven peristaltic mixing pump that simulates the intestine and a sensing system with pressure and flow rate sensors. Solid rocket fuel was successfully produced by a small pump unit. In this study, mixing experiments of solid propellant consisting of several types of powders, including metal powder and highly viscous fluids were conducted using a pump unit with a volume size eight times larger than that used in the previous study. In this experiment, mixing was performed with the materials packed in a plastic bag to increase efficiency. This reduces the contact area between the rubber tube and the contents of the device. Because only part of the mixing process is reflected in the behavior of the device, it is difficult to see differences in the sensor values, and it is unknown whether existing methods can be applied. The results of the experiment showed that the existing sensing system could be used to confirm the differences in characteristics due to the mixing process based on the time series data of air pressure and flow rate. By using Gaussian mixture model, which is a type of clustering, the mixing state was roughly binary discrimination from the acquired sensor values. This suggests that it is possible to estimate the mixing degree in large pumps using existing systems.

This paper formulates the relation between the Phase-Locked Loop (PLL) dynamics of a grid-connected distributed source and the impedance of the grid. Conventionally the design of the PLL for a grid following inverter is performed independently of the grid impedance. With the advent of micro-grids, these design procedures require modification. Microgrids are characterized by higher grid impedances which severely impact the PLL dynamics. The grid voltage in a microgrid is not a stiff variable and thus cannot be assumed to be independent of its interaction with a distributed source. The PLL dynamics in these cases affect the voltage at the point of common coupling (PCC) and vice-versa. In this paper, the relation between the grid impedance and the PLL parameters is analytically derived using dynamic phasors. A distributed resource connected to the grid via a 3-phase inverter is considered for the analysis. Grid synchronization is achieved using a synchronous reference frame (SRF) PLL. It is shown that under weak grid conditions, the PLL can get de-synchronized if the magnitude of grid impedance or the current levels are higher than the thresholds derived in this paper. Microgrids with higher grid impedance are highly susceptible to such situations. The design of SRF-PLL for grid-connected inverters thus needs to include an estimate of the maximum system ratings and the grid impedance.

Submodule losses for Modular Multilevel Converter (MMC) are frequently inferred based only on the number of components. This procedure lacks support because Submodule losses also depend on other conditions. In this work, the simulation of different Submodules with various pulse-wide modulation (PWM) techniques for MMC was performed. A new approach to fairly compare Submodule losses is proposed considering Clamp Single (CS), Clamp Double (CD), Full Bridge (FB), and Cross Connected (CC) submodule topologies. The PWM techniques applied were Phase Shifted (PS), Level Shifted Phase Disposition (LSPD), and Space Vector (SV). In addition, IGBT and SiC MOSFET devices were also considered, and DC sources were used instead of Submodule Capacitors to avoid balancing algorithms. A 9-level Three-phase MMC was developed for simulation purposes. The results show that FB, CS, and CC based MMCs present the same losses when LSPD PWM or SV PWM are applied. CD based MMC shows the overall lowest losses, except when PS PWM and IGBT are used becoming the CC based MMC the lower losses submodule in that case. These simulation results support the importance of taking a holistic approach when comparing Submodules for MMC applications.

Road anomalies, such as potholes and speed bumps, are a nuisance and a source of annoyance to drivers and road users. This nuisance can affect the mobility and fluidity of road transport and can even lead to road accidents. In order to avoid such issues, drivers should be able to notice and be warned of any upcoming anomaly on their path. This paper proposes a safe navigation system called "NaviSaf" that warns drivers of road anomalies on their paths. To stay informed of every new anomaly, NaviSaf utilizes smartphones built-in sensors, machine learning techniques, crowdsourcing and data fusion techniques. Obtained results demonstrate the capacities of NaviSaf to accurately detect and report road anomalies with a precision of around 97%.

This paper proposes a new multi-port flux-modulated permanent-magnet (FMPM) composite machine. The combination of the multi-port and flux-modulated configurations leads to the large torque capacity, high efficiency and fault-tolerant capability. Firstly, the composite flux modulation principle is specifically illustrated, as a general design principle of FMPM composite machines. Specific performance analysis is carried out to demonstrate the electromagnetic characteristics of the proposed machine, with auxiliary of the harmonic analysis. The composite flux modulation effect is proven for effective contribution to the higher torque density of the proposed FMPM machine. As a result, the proposed machine serves as a promising candidate in electric transportation applications.
