Review of GB electricity distribution system's electricity security of supply, reliability and power quality in meeting UK industrial strategy requirements

Abstract

The United Kingdom (UK) Government's 2017 Industrial Strategy outlines a bold plan centred on making the UK one of the most competitive places in the world to start or grow a business, building on the UK's strengths, extending excellence into the future, and closing the gap between the UK's best performing companies, industries, places and people, and those viewed as less productive. In the context of delivering this strategy, from power system reliability and power quality points of view, this paper explores the various challenges and gaps in the Great Britain (GB) electricity distribution system, which is recognised as among the most complex forms of energy exchange that will become the backbone of the emerging digital economy and Industry 4.0. Additionally, the paper also provides recommendations to address the identified challenges.

Flexibility provision of residential energy hubs with demand response applications

“…As a result, the lower-level problem can be independently solved. The lower-level problem's optimal solution can be used to convert the objective function (5) to a new constraint. The optimization problem is then solved in two hierarchical stages.…”

“…However, the presence of RERs in these systems may also overshadow the flexibility of power systems. Variability in output generation of Distributed Generations (DGs) may cause some problems for distribution system operators (DSOs) for example, reverse power flows, congestions, voltages droop, and network losses which need to be covered by flexibility services for example, DSO congestion management, and DSO power quality control [5][6][7].…”

AC Microgrid Protection System Design Challenges—A Practical Experience

“…An electricity distribution system, which connects a large amount of electrical equipment, is among the most complex and sophisticated platforms of energy exchange. An electricity distribution system must also continuously ensure the safety, reliability, stability, power quality, efficiency, and cost effectiveness of electrical power supply to the expectations of its users and to the requirements of governing standards, laws, and regulations [1].…”

“…A convergence of factors, such as deregulation of electricity markets globally, the urgent need to address climate change, the achievement of maturity in modern renewable energy technologies, particularly the wind and solar generation, their low cost, etc., have led a significant shift in the source of electricity generation. This shift in electricity generation has been from bulk centralized transmission system connected power plants to more distributed decentralized distribution system connected Distributed Energy Resources (DERs) [1,2]. In some geographic locations, a shift in the connection of power generation to the distribution systems has been rapid.…”

Belirli Güç Kalitesi Problemlerinin Nesnelerin İnterneti Teknolojileri ile Tespiti ve Bulut Tabanlı Sunuculara Entegrasyonu

“…Böylece büyük veri analitiği ile makine ve ekipman performansı optimize edilerek enerji verimliliği artırılabilmektedir[8]. Şekil 1' de gösterilen IEEE 1159-2009 standardına göre güç kalitesi problemleri ve makalede incelenen uzun süreli RMS değişimlerinden kaynaklanan güç kalitesi problemlerini belirtmektedir[9].Bu çalışmada mini bilgisayar olarak kullanılan Raspberry Pi 3B+ güç kalitesi bozulmalarını tespit eden algoritmanın çalıştırıldığı cihazdır. Sahada güç kalitesi analizi yapılacak noktadan güç parametrelerinin ölçümünü yapmak için Siemens SENTRON PAC 3200 enerji analizörü kullanılmıştır.…”
