A Review of North American Prospects for Power and Hot-Water Generation with Thermal Energy

Received: 20 November 2023;  Published: 21 February 2024;  doi: 10.21926/jept.2401007

Abstract

This article outlines an innovative approach to explore thermal energy extraction for power generation or industrial hot water applications. Unlike traditional steady-state models, this approach embraces time-variant scenarios, explicitly incorporating a cyclical fluid circulation strategy to maintain a stable surface fluid temperature or power output. By introducing an increasing and decreasing stepwise rate sequence and an intermittent circulation strategy, the method aims to optim [...]

Nonlinear Optimal Control for a PMLSG-VSC Wave Energy Conversion Unit

Received: 16 September 2023;  Published: 21 February 2024;  doi: 10.21926/jept.2401006

Abstract

This article aims to treat the nonlinear control problem for the complex dynamics of a wave energy unit (WEC) that consists of a Permanent Magnet Linear Synchronous Generator (PMLSG) and a Voltage Source Converter (VSC). The article has developed a globally stable nonlinear optimal control method for this wave power generation unit. The new method avoids complicated state-space model transformations and minimizes the energy dispersion by the control loop. A novel nonlinear optimal control method [...]

Floating Oscillating Water Column Wave Energy Converters: A Review of Developments

Received: 09 December 2023;  Published: 07 February 2024;  doi: 10.21926/jept.2401005

Abstract

The main challenge in designing offshore renewable energy structures is to ensure their structural integrity on a life cycle basis while operating in harsh environments and, in parallel, being financially competitive and environmentally friendly concerning other types of energy systems. The Oscillating Water Column (OWC) converters are among the first energy converters to be developed and deployed into the sea due to their relative simplicity of operation and relatively small number of moving pa [...]

Monitoring Energy-Loss-Driven-Cost by Using Earned Value Simulation in Complex Systems

Received: 24 July 2023;  Published: 06 February 2024;  doi: 10.21926/jept.2401004

Abstract

The economic impact of energy loss stemming from end-user electricity consumption is a significant concern, with historical trends revealing escalating costs. Effectively managing both peak and off-peak demands remains a formidable challenge due to the unpredictable nature of consumer behaviors, leading to energy wastage. This study delves into the nexus of demand uncertainty, financial repercussions, and potential strategies to mitigate energy losses in the evolving landscape of electricity con [...]

LFO Damping Enhancement in Multimachine Network Using African Vulture Optimization Algorithm

Received: 20 June 2023;  Published: 30 January 2024;  doi: 10.21926/jept.2401003

Abstract

The prolonged presence of low-frequency oscillation (LFO) in power system networks (PSN) poses a significant threat to their stability. Hence, engineers and researchers have continuously developed effective strategies to mitigate the issue and enhance the stability of the PSN. This article proposes a new approach using the African Vultures Optimization Algorithm (AVOA) to design robust Power System Stabilizers (PSS) and enhance the LFO damping in multi-machine networks. The damping ratio-based o [...]

Proposal for the Sustainable Electrification of a Primary Healthcare Centre (PHC) Facility in Nigeria

Received: 06 August 2023;  Published: 24 January 2024;  doi: 10.21926/jept.2401002

Abstract

Energy is a prerequisite to running health facilities and is, therefore, key to the success of the service. Karshi primary healthcare centre (PHC) facility is confronted with an unreliable power supply that leads to a high cost of generating power from diesel to operate its equipment. This facility needs a sustainable and reliable electricity supply and therefore a change in their energy system to enable it improve its quality of healthcare delivery services. A solar energy-based electricity gen [...]
