Outage Management Systems Real-Time Dashboard Assessment Study
Electric distribution companies are faced with increased pressure from customers, the media and regulators to provide accurate outage information that is very timely and essentially in real-time. Distribution owners/operators turn to new technology in the form of Dashboards, Business Intelligence and Outage Management Systems (OMS) to help address these demands. Under ever increasing pressure to improve reliability of electric supply, operations needs to perform restoration faster and more efficiently, driving internal demands for the detailed restoration information to be available in real-time as well. The needs of these internal operational users are typically even more detailed and complex. In addition, regulators are providing financial incentives or penalties based upon reliability goals or Key Performance Indicators (KPI)s. Management is demanding that accurate calculation of progress towards meeting these goals be provided daily or weekly rather than monthly or quarterly. This presentation covers the results of a study into the needs of existing outage management systems users and what they need in a real-time dashboard to meet these new business challenges.
Improving outage restoration efforts using rule-based prediction and advanced analysis
Electric distribution companies are faced with increasing pressure to more effectively manage outages regardless of their source or nature. In pursuit of cost effective solutions, distribution owners/operators turn to decision-malting and process automation through information technology in the form of outage management systems (OMS). The foundation behind outage management systems is the accurate customer-to-electrical service model and reliable prediction of outage locations. This paper discusses the analysis techniques supporting outage management systems relevant to outage predictions, feeder reconfiguration, cold load pick-up, and the effect this has on operations management.
Simulation and control of hybrid renewable energy system connected to the grid
This paper presents a control and simulation of hybrid renewable energy system connected to the grid. The studied system includes a photovoltaic panel, synchronous permanent magnet generator based wind turbine, and a battery for storage energy. The PV array and wind systems are connected to the common DC bus by a boost converter. The battery is connected by a bi-directional DC/DC converter, and then integrated into the AC utility grid via a common DC/AC inverter. In order to extract the maximum energy, a simulation study has been carried out according to the meteorological conditions (wind speed and variable solar irradiance) while maintaining power quality at a satisfactory level. In order to capture the maximum power, a MPPT algorithm is applied for both wind turbine and photovoltaic panel. The modeling and simulation of the whole system has been performed under Matlab/Simulink environment. The obtained results show that the current and the voltage of grid side are sinusoidal and alternative forms, and the power injected to the grid is around the power produced by the hybrid system.
