A fault ride through, power management and control strategy for grid integrated photovoltaic (PV) system with supercapacitor energy storage system (SCESS) is presented in this paper. During normal operation the SCESS will be used to minimize the short term fluctuation as it has high power density and during fault at the grid side it will be used to store the generated power from the PV array for later...
We see two major pains today: new energy sources and energy storage. BG Partners Group and SGiM work on breakthrough solutions to directly address both problems with our proprietary products and in collaboration with our strategic partners. We focus on environmentally friendly fuel cells for distributed, reliable, high quality energy generation and storage as well as heating-cooling cogeneration —...
Smart Grid is a very comprehensive subject which includes the complete energy business line from Generation to Transmission & Distribution to End-Users. The focus of this paper is on the aspects towards the end of this chain, namely smart meters and energy efficiency. Through this paper we will highlight the tangible benefits of Smart Metering and Energy Auditing, outlining the initiative Saudi...
This paper presents an overcurrent protection scheme for a stand-alone PV system consisting of PV array, DC-DC converter, DC-AC inverter, relay and circuit breaker to fed an irrigation load. This scheme is based on a numerical relay which is composed of rms current converter, integrator, comparator, low-pass filter and reset logic. The model of the system is simulated using MATLAB/Simulink. The performance...
Solar power generates proven, predictable and economical energy and new innovations have made solar PV power plants easy to deploy, integrate and maintain. Areas with large solar energy potential are among the dustiest in the world. At first glance, solar would be a natural fit in many of these environments but humidity, airborne dust, and wind of these regions often bring high soiling rates that...
Under deregulated environment transmission congestion is managed in many different ways. Most utilities create; update their own rules of how the congestion is managed. The common output in most cases is temporary congestion relief and higher costs of energy to the end user. Transmission congestion problem is studied from different aspects, i.e. congestion relief, energy price reduction, congestion...
The existing electricity grid is subjected to numerous challenges that are expected to be overcome by Smart Grid. It is expected to provide utility companies with better visibility and pervasive control over their assets and services. There is no full-proof technology that can provide real-time communication in Smart Grid. This paper explores the possible infrastructure for real-time communication...
This paper presents a case study about an Condition Monitoring project for Asset Management implementing an advanced decision process for maintenance and asset replacement in the QATAR electricity distribution network. It describes the principles used to produce an assessment of the health of the entire fleet of assets, together with the concepts retained to prioritize the interventions on the distribution...
Over the last thirty years, Conservation Voltage Reduction (CVR) has been proven to reduce energy consumption and lower demand by 3–5 percent. While these savings have typically been achieved through the application of complex power-flow models, this approach is not well suited to the modern grid (e.g. distributed energy resources, etc.). New technology has been introduced to the market that allows...
This review includes a comparative survey of cleaning mechanisms for solar power plants, with a focus on their application in arid regions. In these regions, dust accumulation can have a severe and detrimental effect on the productivity of solar arrays. The primary concern of this study is to address the need for a commercially viable cleaning solution and present candidate technologies that show...
