Hybrid Power System Design and Dynamic Modeling of Signal Repeater Station on Natural Gas Transmission Network

This paper explores the design and dynamic modeling of a Hybrid Power System (HPS) for Repeater Stations on Natural Gas transmission pipeline networks. These stations transmit crucial data, such as gas flow rates and pressure readings, from remote areas to central control centers. Given their remote locations, ensuring a reliable power supply is crucial. Using the advanced software tool HOMER Pro, the study explores optimization methods tailored to site-specific details. With careful analysis, considering a connected load of 33.65 kWh/d and a peak load of 11.33 kW, the proposed hybrid power system presents a reliable solution for electricity supply while reducing environmental impact. The estimated capital cost of $24,987 and Cost of Energy (COE) of $0.199 per unit underscore the system's economic feasibility, supporting its potential for widespread adoption. The system design undergoes dynamic modeling with MATLAB/Simulink R2022b (MATLAB 9.13) to assess its performance and reliability. Experimental validation includes hardware-in-the-loop (HIL) testing using OPAL-RT Technologies’ real-time OP5707XG simulator.
