Nexor Limited is a privately held company based in Nottingham, providing product and services to safeguard government, defence and critical national infrastructure computer systems. It was originally known as X-Tel Services Limited.
The entire gig ecosystem is pioneering the evolution of a workforce based on a simplistic business model of Flexing; of flexible talent or freelancers. Talent and valued skills are made available on free will by the service provider for a task specified by the service seeker. The sentiment of ‘being your own boss’ plays a crucial role in such an economy. The advent of digital technology has not only multiplied its outreach potential but also carved a way for the emergence of growth opportunities across businesses. However, ensuring the sustainability and security of employment is a challenge. The dexterity of gig workers is to be channelised for a secure future for the informal workforce, which is occurring on an incremental basis with small steps in all major industries, shaping the future trends of workforce formalisation. The recomposition of the workforce is underway with government interventions to provide social security. In this article, we aim to furnish insights on the need for formalisation and its impact on India Inc. We focus on areas like employment of women in the formal sector, the role of new-age start-ups, the implications of newly formed labour codes, the point of view of unions and others that are part of this ecosystem. We explore the potential upgrades on policy changes and industry-specific insights on the gig world covering all the major industries. We propose that it is imperative to deliberate the policies required for ensuring the sustainability of this ecosystem.
As more large thermal generators are decommissioned around the world there will soon be a dearth of large transmission connected generators to provide Black Start (BS) services. BS services need to evolve and determine how Distributed Energy Resources (DERs) can contribute to system restoration. This will require an entirely new and more complex approach to restoration. There are several technical, commercial, regulatory, and operational risks that need to be worked through and mitigated before transition into Business as Usual. These challenges are being explored in Great Britain by the Distributed ReStart innovation project. The paper is based on detailed restoration plans developed as part of the Distributed ReStart project to re-energise a distribution network under a Grid Supply Point using DERs, after a complete system blackout. The restoration plans are developed considering the practical challenges around operation and control of a system which is traditionally restored by a top-down approach. The restoration strategies are guided by extensive steady state, dynamic and transient analyses undertaken on three case study networks in SP Energy Networks (SPEN) distribution license areas.
Black Start (BS) is currently a transmission-led approach of starting large conventional generators with self-start capability and energising a skeleton transmission and distribution network. As large transmission connected fossil fuelled generators are decommissioned around the world to meet the emissions targets, system operators are looking at alternatives for BS services. With increasing penetration of DERs, particularly at 33kV and 11kV (in the UK), it becomes imperative to explore the possibility of using these to support whole system restoration. Different DER control systems such as AVR, Wind Farm (WF) control, etc. are tuned to operate in a strong grid condition with consideration for certain credible contingency scenarios. However, system restoration after a black out is an extreme condition. The short circuit power of the islanded system is limited to only the contribution from the ‘self-starting’ anchor generator. This paper explores the necessary model considerations for BS studies using DERs based on the learnings from the Distributed Restart innovation project.
The overall function of an extended testing platform is to provide accurate parameters for oilfield development,confirm commercial value,reduce exploitation risk and ensure economic benefit.Limited by the overall capacity of the platform's power station,high requirements on the automation of distribution system are called for so as to provide safe,reliable,economical and high quality electric energy.Intelligent power distribution system can effectively improve grid reliability,reduce platform shutdown probability caused by power losing,shorten power recovery time,fasten the finding of fault points and optimize device operating conditions,so as to achieve the goals of energy saving,labor hour and operational risk reduction.This paper intends to make an example of X intelligent power distribution system in a domestic company by applying it to an extended test platform's power supply and distribution system.This may provide a new option for future extension of power system design for the test platform.
This paper not only established a geometric model of camera imaging equipped with core image collection system,but also analyzed the principle of sampling head distortion.To eliminate the two main kinds of geometric distortion of this system,and deduced a transformation formula,this paper proposed one method which is based on geometric transformation and linear compensation.At the same time,experiments also show the method can collect the core images effectively,satisfy the post-processing analysis requirement of images,has higher practical value on project.
