Abstract

Wireless LAN (WLAN) network quality in indoor environments is significantly affected by distance, building conditions, and physical obstacles such as concrete walls, glass, and other materials. Manually testing WiFi signal quality at multiple points is repetitive, time-consuming, and potentially leads to data inconsistencies. Therefore, this research aims to design and build a WiFi service coverage area testing system using a Raspberry Pi 3-based remote-controlled wheeled robot as a more efficient and controlled measurement alternative. The robot functions as a mobile platform that acts as a WiFi client to measure Received Signal Strength Indicator (RSSI) values ​​at various coordinate points in the test environment. The system was developed using a Raspberry Pi 3 as the control center, Python programming for the control system and RSSI reading using the PyWiFi library, and OpenCV for real-time camera display. The robot is controlled via a remote interface and moves according to a predetermined coordinate scheme. Tests were conducted at 35 measurement points, comparing the RSSI results from the robot prototype with the WiFi Analyzer application on an Android device. The test results show that RSSI variations are influenced by the distance from the access point and the physical environmental conditions. Data comparison shows an average error percentage of 5.51%, which indicates a system success rate of 94.49%.

Abstract

Load Frequency Control (LFC) plays an essential role in maintaining frequency and power stability in power generation systems under load disturbances. Variations in load demand, such as increases or decreases, may lead to power deviations that affect system reliability; therefore, an effective control strategy is required. This study evaluates the performance of an LFC system by comparing a Proportional–Integral–Derivative (PID) controller and a Fuzzy Logic Controller (FLC). The system is modeled based on the dynamic characteristics of the governor, turbine, and generator of a coal-fired steam power plant. System performance is analyzed under three operating conditions: no disturbance, load increase, and load decrease. The evaluation focuses on maximum power deviation and settling time as performance indicators. Simulation results show that both controllers are able to maintain system stability but with different dynamic characteristics. Under no-disturbance conditions, the PID controller reaches stability faster with a settling time of 18.126 s, while the FLC requires 28.038 s. During load increases, the PID-controlled system stabilizes at 194.652 s, whereas the FLC reaches stability at 200.524 s. For load reductions, the PID controller stabilizes at 194.378 s and the FLC at 196.559 s. In terms of maximum power deviation, the FLC produces a smaller deviation (0.41%) compared to the PID controller (0.47%). These results indicate that the PID controller provides faster recovery, while the FLC offers smoother responses with smaller deviations, showing potential for improving LFC performance.

Abstract

In recent years, energy management has become an essential issue in the growing integration of microgrids, enabling more efficient and sustainable energy use. This research focuses on optimizing microgrid networks to achieve economic dispatch using the Grasshopper Optimization Algorithm (GOA). Economic dispatch aims to minimize total generation costs while meeting load demand. Traditional methods such as Particle Swarm Optimization (PSO), Priority List (Merit Order), and the Lagrange method have been widely used. Still, GOA offers superior performance potential in cost efficiency and computational effectiveness. This study compares the efficacy of PSO, GOA, Priority List, and the Lagrange method in optimizing microgrid operations through a series of simulations. Key performance metrics include total generation costs, convergence rates, and computation time. The results showed that GOA was superior to PSO and Priority List in reducing generation costs, with differences of $3.8 per hour of generation compared to PSO and $39.8 per hour of generation compared to Priority List. Additionally, GOA has a more adaptive convergence rate. However, the Lagrangian method does not apply to all objective functions, making it less effective for solving economic dispatch problems. In conclusion, GOA could significantly improve the economic efficiency of microgrid systems, contributing to more sustainable and cost-effective energy management. The combination of various optimization methods, such as GOA, PSO, and others, offers a more comprehensive approach to facing future energy management challenges.
