The phasor measurement unit (PMU), with its ability to directly calculate synchronized positive sequence voltages and currents (magnitude and phase), offers a more current and accurate view of the power system compared to that provided by traditional measurements and state estimation (SE). However, the high-resolution data, provided at rates of 50 Hz and 60 Hz (dependant on nominal frequency), capture...
This paper describes a Combined Cooling, Heating and Power Plant (CCHP) that was designed and commissioned to supply a commercial building that hosts a data centre, which requires the availability of 99.995%. The main objective of this paper is the study of the two control systems of the CCHP in order to output electricity but also heating and cooling: hot water, heating, cool water, cool air, with...
Nowadays, power systems face more challenging network wide issues with regard to ensuring secure and reliable operation. Therefore, having a wide area monitoring system is a vital need in order to detect problems and react on them as quickly as possible. An important component when providing wide area monitoring and control for transmission networks is the SCADA system, which connects the substations...
A crucial question is “How complicated can, or should, a dynamic electricity tariff be?” such that it is acceptable to consumers, and offers clear benefits to both consumers and network operators. The ‘can’ and ‘should’ reflect the fact that any ubiquitous technical system is (primarily) designed and implemented by experts, but has to be accepted and operated by non-experts. ADEPT is examining how...
As the challenges associated with delivering reliable electrical power in the world are increasing, the mixture of 'fast response time' and 'distributed data sources' may cause scalability issues with the traditional approach that mostly uses centralized communication infrastructure. Due to tremendous demand growing in the future, the centralized approach will become less efficient. Therefore, this...
The classification of power systems operating states plays an important role in power systems control and operation. Determining the state of a power system is crucial and requirements for real-time decision making in power systems security assessment demand low dimensionality and low computational time. This paper investigates the performances of feature extraction based on mutual information in...
Power systems operate in a more complicated condition than they used to. Changes in the wholesale electricity market alongside the difficulties in upgrading the transmission system have caused transmission systems to face more challenging network wide issues. Therefore, having a Wide Area Measurement System (WAMS) is vital with regard to ensuring secure and reliable operation. Traditionally, Supervisory...
