Repair strategies for minimising the risk of cascading failures in electricity networks
In this work, we develop repair strategies for simplified models of electric power grids. The goal is to gain insight into the combinatorial properties of repair problems in order to improve maintenance and restoration planning. Firstly, we consider a seriously damaged grid and try to find the set of lines that should be repaired first in order to resupply the customers as fast as possible. We ...

Market power monitoring under open access system
In this paper, an engineering procedure is proposed for complete market power monitoring under open access system. Market power monitoring of any given system or network is done by using market power assessment and market power indices. For any given network, market power assessment is to identify which generation company (GENCO) raised their prices when the demand in the concerned area is ...

How does a standby / backup generator work?
Power failures are inevitable, whether due to technical issues or adverse terrain and weather conditions. Standby generators or emergency run generators are used to, in situations like these, fill in as the main source of energy in the event of a network failure. Having an alternative source of electricity is a useful and often highly necessary option, with many sectors and activities relying on ...

Have you ever heard of the dual source energy meter ?
The dual source energy meter usually refers to an energy meter that can simultaneously measure the input or output of two different types or sources of energy. This type of meter is particularly suitable for hybrid energy systems, such as those with traditional grid power and renewable energy sources (such as solar, wind, etc.), as well as diesel power generation.The following are some ...

Wind energy and system security – the grid connection moratorium in Ireland
This examines the interaction between technical challenges and policy choices that are made regarding wind power, and uses the grid connection moratorium in Ireland as a case study. While total installed wind capacity in Ireland is low compared with Germany, Spain and Denmark, wind power penetration is higher in the Irish system than in either the British, UCTE or NORDEL systems. In December 2003 ...
