Static Security Assessment and Contingency Analysis for Smart Grid

The Power System is a complex network of transmission lines, transformers, circuit breakers, and other components. As a result, the system must be safe and dependable from generation through distribution, with a continuous power supply required from generation to consumer end. However, several variables may disrupt the power supply regulations, resulting in system failure or collapse. When the system is functioning in a steady-state condition, the parameters Bus voltage and Frequency magnitude are kept within the level to prevent these defects and failures. This is known as power system security. The required power supply without interruptions saves our domestic equipment and increases the overall performance of the system. Some of the factors that affect our power system like Poor power quality can also cause issues with electromagnetic compatibility and noise. It can cause sophisticated protective systems to malfunction or fail, as well as key control and communication systems to malfunction or fail. Connected power demands, such as lighting, heating, and motors, are less sensitive to fluctuations in supply voltage and more sensitive to supply availability (absence of interruptions). Electronic or digital equipment, on the other hand, is more sensitive to fluctuations in supply voltages. Voltage fluctuation, harmonic distortion, voltage imbalance, flicker, supply interruptions, voltage sags, voltage swells, and transients, among other things, all have an impact on power quality. The system’s load requirement is completed by balancing between real and reactive power. various power problems are generated in the power grid because of long power transmissions such as trees falling on line, snowfall, lightning strokes, and flooding with the equipment failure may happen. These power problems may affect the technological power devices that generated faulty distribution systems with some electrical noise. Like hissing noise, corona, and line losses also. So, from this, we prevent system failure and uninterrupted power supply by using some monitoring and controlling methods and providing fine power to our smart grid this helps us to maintain electrical power and sustainability for a reliable electrical power system.
