The integration of renewable energy sources into the distribution grid may cause more profound voltage deviations and overloading of grid elements. In certain countries (for example, Belgium), a lot of photovoltaic systems are connected to the low-voltage distribution grid at household residences. These renewable energy sources may cause excessive voltage increase at times when also the load is...

This paper analyses the effects of doubly fed induction generator (DFIG) tidal current turbines on a distribution grid under unbalanced voltage conditions of the grid. A dynamic model of an electrical power system under the unbalanced network is described in the paper, aiming to compare the system performance when connected with and without DFIG at the same location in a distribution grid. Exte...

This paper focuses on two areas that experience in building databaseoriented e-science applications has shown to be important. Firstly, methods of promoting data locality are vital due to the high cost of moving data in servicebased distributed systems. Databases provide an excellent basis for achieving this due to their potential for moving computation to data. The paper also describes a new i...

Natural disasters such as earthquakes, hurricanes, and other extreme weather pose serious risks to modern critical infrastructure including electrical distribution grids. Recent U.S. government sources [1, 2] suggest that new methodologies for improving system resilience to these events is necessary. Here, we focus on developing methods for designing and upgrading these grids to better withstan...

Distribution Substation Automation in Smart Grid Substation Automation (SA) can provide integral functions to the distribution grid automation. As more IED devices are installed to the distribution network, the need for IED management, control, and the corresponding advanced application operation is a growing imperative. Moreover, the Smart Grid applications, such as the Integrated Voltage and ...

This paper suggests a new Grid computing architecture using programmable routers with network processors to distribute computing tasks at wire speed in a grid. Task Message datagrams containing code and data, but without explicit destination addresses are sent across the network, e.g. the Internet, and are immediately routed to the most appropriate computer by the network processors. Only a ret...

In a smart distribution power grid, cost efficient and reliable communication architecture plays a crucial role in achieving complete functionality. There are different sets of Quality of Services (QoS) requirements for different data packets transmitting inside the microgrid (a regionally limited smart distribution grid), making it challenging to derive optimal communication architecture. The ...

It is essential to estimate how much power can be delivered from vehicles to grid, called achievable power capacity (APC), for practical vehicle-to-Grid (V2G) services. We propose a method of estimating the APC in a probabilistic manner. Its probability distribution is obtained from the normal approximation to the binomial distribution, and hence represented with two parameters, i.e., mean and ...

A robust methodology for obtaining the steady-state solution of the power grid is essential for reliable operation as well as planning of the future transmission and distribution grid. At present, disparate methods exist for steady-state analysis of the transmission (power flow) and distribution power grid (three-phase power flow). All existing alternating current (AC) power flow and three-phas...
