Machine learning (ML) for transient stability assessment has gained traction due to the significant increase in computational requirements as renewables connect power systems. To achieve a high degree of accuracy; black-box ML models are often required – inhibiting interpretation predictions and consequently reducing confidence use such methods. This paper proposes SHapley Additive exPlanations...

Substation (SS) auxiliary systems (SAux) are facilities responsible for hosting the alternating (AC) and direct current (DC) busbar to serve equipment that perform substation’s protection, control, supervision. External internal power supplies typically ensure continuity of such a facility. The electricity support will be restricted diesel emergency generators (DG) if external supply is unavail...

The collaboration between the Solar Energy Research Institute of Singapore (SERIS), Trina Solar and ANU is progressing well, and ANU has already developed all-back-contacted (ABC) silicon wafer cells with best one-sun efficiencies of 21.2% and 22.1% on FZ material, when measured with the aperture areas of 16 cm (includes busbars) and 13 cm (excludes busbars) respectively. This paper presents th...

The application of voltage reduction in medium and low grids to reduce peak power demand or energy consumption has been implemented since the 1980s using several approaches. Conservation Voltage Reduction (CVR), as one such approach, uses a control device increase setpoint on busbar, thereby reducing increasing amount active reactive supply network. regulation for CVR is always according establ...

Nowadays, large-scale solar penetration into the grid and intermittent nature of PV systems are affecting operation distribution networks. This paper aims to investigate effect on a typical medium-voltage network in Malaysia. The main objectives this study voltage stability, power loss, short circuit under two conditions: peak load no load. is evaluated using methods: static dynamic analysis, u...

Electrical utilities performance is measured by various indicators, of which the most important are very dependent on interruption time after a failure in network has occurred, such as SAIDI. Therefore, they constantly looking for new techniques to decrease fault location and repair times. A possibility innovate this field estimate failed component when occurs. This paper presents conclusion an...

an electric arc furnace (eaf) is known as nonlinear and time variant load that causes power quality (pq) problems such as, current, voltage and current harmonics, voltage flicker, frequency changes in power system. one of the most important problems to study the eaf behavior is the choice of a suitable model for this load. hence, in this paper, a probabilistic three-phase model is proposed base...

The last years blackouts have indicated that the operation and control of power systems may need to be improved. Even if a lot of data was available, the operators at different control centers did not take the proper actions in time to prevent the blackouts. This depends partly on the reorganization of the control centers after the deregulation and partly on the lack of reliable decision suppor...

In the past few years, technical progress has determined traditional electric power system conversion to Smart Grids, and consequently empowered a worldwide renaissance in forgotten PQ field. Since installation of monitors is currently associated with high investments operational costs, it inappropriate install monitor on each grid busbar. Hence, operators must establish best cost–benefit scena...
