INTRODUCTION TO POWER SYSTEM STABILITY BY Kundur Power Systems SolutionsPower System Operation
Power System Stability denotes the ability of an electric power system, for a given initial operating condition, to regain a state of operating equilibrium after being subjected to a physical disturbance, with all system variables bounded so that the system integrity is preserved
Integrity of the system is preserved when practically the entire power system remains intact with no tripping of generators or loads, except for those disconnected by isolation of the faulted elements or intentionally tripped to preserve the continuity of operation of the rest of the system
Stability is a condition of equilibrium between opposing forces:
instability results when a disturbance leads to a sustained imbalance between the opposing forces
instability is a run-away or run-down situation

Abstract:
The Modelica language, being standardized and equation-based, has proven valuable for the for model exchange, simulation and even for model validation applications in actual power systems. These important features have been now recognized by the European Network of Transmission System Operators, which have adopted the Modelica language for dynamic model exchange in the Common Grid Model Exchange Standard (v2.5, Annex F).
Following previous FP7 project results, within the ITEA 3 openCPS project, the presenters have continued the efforts of using the Modelica language for power system modeling and simulation, by developing and maintaining the OpenIPSL library: https://github.com/SmarTS-Lab/OpenIPSL
This seminar first gives an overview of the origins of the OpenIPSL and it’s models, it contrasts it against typical power system tools, and gives an introduction the OpenIPSL library. The new project features that help in the OpenIPSL maintenance (use of continuous integration, regression testing, documentation, etc.) are also described.
Finally, the seminar will present current work at LNLL that exploits OpenIPSL in coordination with other tools including ongoing work integrating openIPSL models into GridDyn an open-source power system simulation tool, as well as a demos of the use of openIPSL libraries in GridDyn.

SolarEdge Technologies provides next generation power conversion electronics that effectively remove the known system constraints across the photovoltaic energy space. Our Smart DC ASIC technology and active electronics enable cost efficiency and an increased production of clean, grid-ready energy. SolarEdge presents a unique, patent-pending distributed solar power harvesting system, comprised of the following elements:
SolarEdge Power Optimizer
The SolarEdge power optimizer is integrated into each module, replacing the traditional solar junction box. The SolarEdge power optimizers maximize energy throughput from each and every module through constant tracking of the Maximum Power Point individually, per module. Furthermore, the power optimizers monitor the performance of each module and communicate performance data to the SolarEdge monitoring portal for enhanced, cost-effective maintenance. When working with SolarEdge inverters, power optimizers automatically maintain a fixed string voltage, allowing optimal efficiency of the SolarEdge inverter and giving installers greater flexibility to design optimal PV systems.
The independent optimization (IndOP™) technology allows power optimizers to be installed without the need for additional interface hardware and to operate directly with any inverter.
Each power optimizer is equipped with the unique SafeDC™ feature which automatically shuts down modules' voltage whenever inverter or grid power are shut down.
SolarEdge PV Inverter
The SolarEdge Inverter is a highly reliable DC-AC PV inverter. Because MPPT and voltage management are handled separately for each module by the power optimizer, the inverter is only responsible for DC to AC inversion. Consequently, it is a less complicated, more reliable solar inverter. The fixed string voltage ensures operation at the highest efficiency at all times (>97% weighted efficiency) independent of string length and temperature.
SolarEdge PV Monitoring Portal
A web-based application provides module-level, string-level and system-wide monitoring. The solar monitoring software automatically provides alerts for accurate fault detection, localization and remote troubleshooting at the module level. Module performance is communicated across existing power lines, so no extra wiring is required.
Solectria Smart Inverters, Effective Grounding, and how to work with the UtilityClaude Colp
Presentation focused on educating solar developers, engineers, and utilities to the benefits of adding solar to the power grid. With some added protection, power factor correction, and remote shutdown capabilities PV installers are now able to interconnect on more distributed generation that was originally thought to be unsuitable.
At Ornate Solar, we believe that with every solar panel and inverter that we sell, we help India move one step closer to a sustainable future.
SolarEdge is an intelligent inverter solution that is revolutionising the way power is harvested and managed in a solar photovoltaic system.

The web-based monitoring portal provides enhanced PV performance monitoring and yield assurance through immediate fault detection and alerts at module level, string level and system level.
No hardware or wiring is required to transmit data from the power optimizers to the inverter: the monitoring sensors and transmitters are built into the EPCS power optimizer and solar inverter, and measurement data is transmitted over the regular power lines.
