    deals with the important issue of transmission system congestion management with consideration of voltage stability as a load ability limit. Congestion is defined as a whenever the physical or operational constraints in a transmission network become active, the system is said to be in a state of congestion. The possible limits that may be hit in case of congestion are: line thermal limits, transformer emergency ratings, bus voltage limits, transient or oscillatory stability, etc. • Thermal limit: -The maximum amount of electrical energy that transmit on transmission line without overheating. • Voltage limit: - System voltage and change in voltage must be maintained with the range of acceptable deviation.…

    fuels. Another challenge has been substantial repercussions from climate change policy on the electrical power markets. This challenge has resulted in the need for addition of intermittent energy sources such as wind and power. Integration of renewable energy sources (RES) is hampered by the fact that most distribution networks have a very low degree of monitoring and automation. These challenges led to an urgent need to come up with a power grid that rises up to these challenges. A class of…

    theory of power transfer network We know that AC lines are operated at voltage level between 10kv to 800kv. The distribution network operates voltage level below the 100kv. For protection against fault circuit breakers are used. Power flow is obtained by receiving end power or sending end power. Ex. Consider a transmission line connected between load centre and generating station. We assume line is loss less and ignore line charging, then the power flow (P) is, P=V1V2 sin⁡(θ1-θ2)/X…

    The light bulb is one of Thomas Edison’s most famous engineering innovations. However the “Wizard of Menlo Park” (a name which he was also known as) has created and/or designed so many more inventions than just the light bulb. He has about 2332 patents worldwide proving he was really a great inventor. However, what proved his amazing skilling creating/designing are the useful products that are used throughout society till date. Edison’s inventions/designs such as the first electrical power grid,…
