As electric utility companies grapple with the need to reduce greenhouse gas emissions and the increasing costs and lead-times for introducing new generating capacity they are turning to the concept of the smart grid. One of the core elements of the smart grid is the smart power meter that communicates with both the energy supplier and the cons

umer to provide real-time information on energy consumption and cost. The energy supplier`s biggest headache is catering for the peak loading on their electric network. Peak loads can be related to user demand, such as air conditioners in hot weather, or may be the result of equipment outages. The smart grid`s aim is to reduce the impact of peak loading both by changing user behavior and by directly controlling the consumer`s equipment. By leveling out the network load, utilities can more efficiently manage their generating and transmission capacity, saving cost and reducing emissions. Deploying the smart grid should provide equitably priced electricity for all customers through enhanced security, quality, reliability, and availability of power. Smart meters communicating with a smart network will allow the utility to implement a variety of control and incentive programs, such as real-time variable pricing. With features like in-home energy displays or eco-panels, the consumer can be warned when a peak loading rate is being charged. They can then make an informed choice to switch off appliances such as dryers and postpone their use until a lower rate is available. With smart appliances or Demand Response Units (DRUs) controlling appliances in the home, the rescheduling of high consumption functions can be controlled directly by the utility via the smart meter. The smart grid is no empty promise it is coming now and the...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
