If a company wants to reduce its energy costs, its primary focus should be on reducing energy consumption. However, in many cases, companies can also realize significant savings by optimizing both their energy consumption profile and their energy contract and purchasing strategy.
It all starts at the engineering phase: operational energy efficiency can be increased by properly dimensioning installations and components. At the same time, the costs associated with an over-dimensioned grid connection can be avoided by accurately forecasting the simultaneity of electrical loads. The combined effect is a lower overall energy commodity cost and a reduction in the capacity component on the invoice.
A company can gain a better understanding of its consumption profile through energy monitoring. Once this valuable insight is in hand, it can identify both problems and opportunities in terms of time-flexible consumption. Among other things, this application note will discuss various ways of adjusting consumption. A company can optimize its purchasing strategy, especially for year-round, seasonal or monthly base load demand. In addition, it can flatten its consumption profile through (automated) peak shaving, thus further reducing various tariffs and peak load penalties. Such evaluations often also lead to optimized production planning. Practical examples of load management will be discussed in this application note.
Another advantage of load management is the ability to increase the benefits of local (renewable) electricity generation through optimized self-consumption. This helps avoid costs (or lack of savings) for injecting overproduction onto the grid.
Finally, load management may enable a company to valorize its flexibility of consumption on the energy market, either directly on spot or imbalance markets or through aggregated demand response.

The significance of power factor correction (PFC) has long been visualized as a technology requirement for improving the efficiency of a power system network by compensating for the fundamental reactive power generated or consumed by simple inductive or capacitive loads. With the Information Age in full swing, the growth of high reliability, low cost electronic products have led utilities to escalate their power quality concerns created by the increase of such “switching loads.” These products include: entertainment devices such as Digital TVs, DVDs, and audio equipment; information technology devices such as PCs, printers, and fax-machines; variable speed motor drives for HVAC and white goods appliances; food preparation and cooking products such as microwaves and cook tops; and lighting products, which include electronic ballasts, LED and fluorescent lamps, and other power conversion devices that operate a variety of lamps. The drivers that have resulted in this proliferation are a direct result of the availability of low-cost switch-mode devices and control circuitry in all major end-use segments: residential, commercial, and industrial.
In order to keep power quality under the limits proposed by standards, it is required to incorporate some sort of compensation. There are two basic types of PFC circuits: active and passive. The simplest power factor correctors can be implemented using a passive filter to suppress the harmonics in conjunction with capacitors or inductors to generate or consume the fundamental reactive power, respectively. Active power factor correction circuits have proven to be more effective, generally integrated with the switch-mode circuitry, and actively control the input current of the load. This enables the most efficient delivery of electrical power from the power grid to the load. The demand for new smart, green products has set the stage for a worldwide migration from antiquated passive circuits to active correctors as well as from traditional analog technology to digital techniques. New digital active power factor correction delivers better full- and light-load power efficiency while lowering system costs, enabling smaller designs and providing a clear path for further feature enhancements and improved competitive positioning for a whole host of consumer and industrial products. Cirrus Logic’s novel advances in digital active PFC technology signify a major enabling element in the development of the newest generation of low cost, energy-efficient switch mode products.

Main component parts of the overhead line
The most effective method of providing protection to transmission lines against direct lightning strokes is by use of overhead ground wires as shown in Fig 6. For simplicity, one ground wire and one line conductor are shown. The ground wires are placed above the line conductors at such positions that practically all lightning strokes are intercepted by them (i.
e. ground wires). The ground wires are grounded at each tower or pole through a low resistance as possible. Due to their proper location, the ground wires will take up all the lightning strokes instead of allowing them to line conductors. The degree of protection provided by the ground wires depends upon the footing resistance of the tower.

Intelligent Substation & its applicationsGowtham MG
The document presents a blueprint for a smart grid community. It describes how a smart grid uses two-way digital technology to deliver electricity from producers to consumers and allow control of appliances and machines. This is an upgrade from the traditional one-way electricity grids. Key features of the smart grid include improved reliability, security, environmental benefits, support for distributed generation, and helping customers control energy use. The smart grid incorporates smart substations using digital controls, energy storage, smart distribution assets, smart homes, and electric vehicles. Benefits include faster response to outages and lower prices through reduced energy usage. Developing the smart grid will cost $60-100 million but be offset by partnerships and cost savings over the long run.
Distributed energy resources (DERs) are a solution for many challenges in the electric power grid. Primary drivers of their adoption include an aging infrastructure (requiring significant capital expenditure), capacity constraints where traditional utility upgrades may not be feasible or economical, and localized demands on utility distribution infrastructure (due to customer choice to add solar photovoltaic (PV), energy storage, or electric vehicles). The operational profile of these technologies, when observed as a collective group, are often characterized by random load/generation profiles which can create disturbances in supply voltage and power quality, ultimately impacting the safety and reliability of power delivery.
One of the prominent sources of renewable energy in widespread use is solar photovoltaic (PV) power generation. The high penetration of PV based DERs is threatening the reliability of power delivery due to intermittency (result of cloud coverage) and lack of temporal coincidence of maximum production with peak load. Energy storage is one way to address this problem.

The document discusses current limiting transformers. Current limiting transformers limit secondary current under short circuit conditions by using core gaps in the magnetic shunt paths. This prevents damage to secondary windings or loads from infinite current in short circuits. They work by bypassing increased flux from a short circuit through an iron core placed between transformer limbs. Current limiting transformers have distributed primary and secondary windings and increased leakage inductance from an extra flux path between core limbs. This limits current without dissipating power. The transformer discussed has three functions - voltage transformation, fault current limitation, and voltage regulation as a substitute for other equipment.

Micro-alloyed copper overhead line conductors - Wire & Cable Technology Inter...Leonardo ENERGY
http://www.bluetoad.com/publication/?i=217299&p=90
Overhead line conductors are traditionally a domain for aluminium, using either steel reinforced aluminium or aluminium alloys. Using copper for overhead lines might surprise some people because it is a substantially heavier material. Weight, however, is not the most crucial characteristic of the conductor. Its smaller section and hydrophobic coating reduces the wind and ice loads on the conductors, which makes the overhead line more resistant and resilient to weather conditions.
Also, the higher conductivity of copper reduces the losses and the life cycle cost of the overhead line.
Variable frequency drives (VFDs) are prone to failure of the power cable connecting the VFD to the motor. While the power electronics in VFDs are now very reliable, cables lack protections and can fail when subjected to electrical or mechanical stresses from VFD operation. Engineers can avoid costly downtime from cable failures by carefully selecting cable materials, ensuring proper shielding and stranding, and accounting for mechanical loads in industrial settings. Paying attention to cable construction details that match the electrical and environmental demands of the VFD application can maximize reliability and performance of the overall drive system.
Variable frequency drive (VFD) systems can cause costly downtime if they or their connecting cables fail. While VFD electronics have become reliable, cables are more vulnerable because they lack protections from voltage spikes and other power issues. Selecting cables designed for VFD applications, with materials like semiconductive insulation that reduce voltage stress, optimized stranding to lower resistance, and shielding against electrical noise, can help avoid cable failures and improve overall drive system performance and reliability.

IRJET- Transmission of Ac Power from Offshore to Onshore by using Low Frequen...IRJET Journal
This document discusses the transmission of AC power from offshore wind farms to onshore grids using low frequency AC transmission. Some key points:
1) Offshore wind farms generate power at medium voltage DC which is converted to low frequency AC (e.g. 20Hz) using cycloconverters for transmission through undersea cables.
2) At the receiving end, the low frequency AC is converted back to standard grid frequency AC using phase shift transformers before connecting to the onshore grid.
3) Low frequency AC transmission allows use of the same undersea cable designs as used for standard frequency but increases transmission capacity and distance. It provides an alternative to HVAC and HVDC transmission for medium length offshore connections.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
