Smart grid literature shows a potential way to implement smart grid using Multi-Agent System (MAS) which is a distributed computational intelligence technique that comprises of multiple interactive intelligent agents in an environment. This paper presents an application of MAS technique for improving the efficiency and optimizing the energy usage of smart homes. The smart appliances in a smart home...
The existing Ancillary Services (AS) in the Electric Reliability Council of Texas (ERCOT), Texas Independent System Operator (ISO), were developed in the late 1990s based on inherent characteristics of conventional synchronous generation in the grid. ERCOT system and its generation mix have undergone significant changes over the past two decades. Therefore ERCOT staff and stakeholders are currently...
For the complex structure of the large capacity turbo-generator in end region, the accurate calculation of the leakage magnetic field became key factor in large generator design. Affected by the leakage magnetic field, there is a problem that the end stator ladder packets, copper screen, press plate has a local high temperature. The three-dimensional electromagnetic field of a 330 MW water-hydrogen-hydrogen...
Since intermediate mechanical conversion mechanisms for speed, torque and motion conversion can be entirely eliminated, the direct-drive wave power generation attracts more and more attention [1]. Among various proposed generators, the permanent-magnet (PM) vernier generator is considered as a viable solution for the wave energy harvesting. This generator can efficiently harness this low-speed and...
Wireless Sensor Networks (WSNs) have undergone rapid advancement over the past few decades. Typically, batteries power these wireless sensors. However, in many cases, battery life is preventing the WSNs from being widely applied. The power supply bottlenecks of WSNs would be solved by the self-powering sensors completely. As vibration energy is ubiquitous, energy harvesting from environment vibration...
High penetration of variable generation such as wind power increases the demands on frequency control. The same applies to island operation and in particular if this involves variable generation, which is planned at the Danish island Bornholm. While it is obvious that the frequency control need to be considered, the disturbances caused to this control by the hourly dispatch of generation has received...
In this paper an encoder/decoder pair with memory is designed for fault detection (FD) over networks. The basic idea is to estimate the support of the difference between the process measurement and the estimated one. Then by applying quantization with a uniform quantizer a symbol representing the quantization cell is transmitted. Firstly the channel without packet loss and bit errors is considered...
To transform endless energy from ambient vibration into useful power. We scavenge mechanical energy and transfer into electrical energy by utilizing piezoelectric materials. We compare generators performance at different situations and then let electric energy be charged to a Ni-MH battery or a capacitor through a full wave rectifier. We also obtain resonance of piezoelectric benders by system identification...
