Microhydro-Electric Systems Simplified
If you have a suitable site, harnessing the energy in a stream or creek can be the most cost-effective way to make renewable electricity. Compared to the sun and wind’s variability, a stream’s flow is relatively consistent, making microhydro-electric system output the most predictable of all the renewable energy (RE) electrical ...

Non-supply of electricity in resource constrained electricity systems
Shortages in the supply of electricity in resource constrained electricity systems of developing nations is a poorly documented but commonly observed phenomena. The literature on electricity systems has a perspective on the issue of interruptions in the supply of electricity that focuses on the high cost of unpredictable but infrequent interruptions. This "reliability" perspective does ...

Water Rights: A Microhydro Evolution
Every morning, before brushing teeth or having a look at the weather outside our Victoria, Australia, off-grid home, my wife Carrie or I pad downstairs to the battery room to check the meters that monitor our electrical system. ...

Electricity demand analysis - unconstrained vs constrained scenarios
In India, the electricity systems are chronically constrained by shortage of both capital and energy resources. These result in rationing and interruptions of supply with a severely disrupted electricity usage pattern. From this background, we try to analyse the demand patterns with and without resource constraints. Accordingly, it is necessary to model appropriately the dynamic nature of ...

The effects of dynamic residential load participation: penetration levels for operational impact on reliability
Building an electrical load system that uses prioritised loads has been suggested as a means of approaching the overloading of the aging electrical infrastructure and thus increasing system reliability. In this paradigm, local controls would shut off electrical loads when overload conditions are being approached in the electrical power system. An unresolved question is how these systems might be ...

Case Study: IKEA Richmond
IKEA is an international home furniture retailer. IKEA recognizes that reducing energy consumption is a smart business decision; reducing energy consumption is both good for business and the environment. IKEA installed a Harmonizer-AVR in their Richmond BC location and experienced an immediate energy savings. Challenge: Reduce energy consumption in a large facility with a mix of retail and ...

Socio-technical implications of domestic microgeneration technologies in the UK electricity system
New technologies will play a crucial role in the transition to a sustainable energy system and a low or zero carbon economy more widely. Microgeneration technologies are one potential contributor to a sustainable energy system. From a Large Technical System (LTS) perspective, this paper explores the systemic challenges to increase the share of decentralised domestic microgeneration technologies ...

Societal reaction to the power frequency electric and magnetic field effects of electric utility systems
The power frequency electric and magnetic field (EMF) effects are associated with the transmission and distribution lines of electric utility systems, and also with work environments, office machines, illumination sources, home appliances, computers, etc. Most of these facilities are considered indispensable components of everyday life in population centres, office complexes and industrialised ...

Hidden failures in electric power systems
Hidden failures in equipment are those failures which occur at random and that do not lead to any discernible change in the state of the network and, therefore, remain undetected. Although hidden failures can occur in any equipment, the hidden failures in protective equipment have attracted a good deal of attention in recent years. Admittedly these failures are rare but, when the power system is ...

Policy and economic issues of electrical power and energy systems
During the last quarter of the 20th century, many developments have served as catalysts for changes in the national energy policies of countries throughout the globe. These catalysts have affected the institutions and energy framework of virtually every country. In the majority of countries, the predominant electricity supply institution is the electric utility monopoly characterised by some ...

Control of the regimes of the electric power systems and deregulation
This paper presents a survey of characteristics, balances, stabilities, reliability and regimes of Electric Power Systems (EPS) and Interconnected Electric Power Systems (IEPS). They are the most complicated and important 'machines' that have ever been created by humankind. Introduction of deregulation in the EPS will require and impose new systems, new algorithms and new rules for control. EPS ...

Discrete event simulation of the post-earthquake restoration process for electric power systems
This paper describes a discrete event simulation model of the post-earthquake restoration process for electric power systems. The model explicitly represents the real-life restoration process, enabling development of geographically disaggregated, quantitative restoration curves with uncertainty bounds, a dynamic map showing the spatial distribution of outages changing over time, and information ...

An analysis of spatial pricing and renewable generation in the British electricity system
This paper investigates the importance of implementing adequate locational signals and their possible effects on the development of renewable energy sources. In particular, the paper investigates a potential conflict in the British electricity system between the introduction of more efficient spatial pricing and the development of wind energy in the north of the country. The regulatory and ...

Advances in efficiency optimisation control of electrical servo drive
The development of legislative acts in the world in favour of environmental protection requires the reversion of electrical drives' specifications. Indeed, the efficiency of electrical systems has become a crucial goal in the design of control systems (Farhani et al., 2012). In this perspective, this paper proposes a new control strategy of the association of the asynchronous machine and its ...
