The foremost issues of 21 st century are challenging demand of electrical energy and to control the emission of Green House Gases (GHG) emissions. Renewable energy resources based sustainable microgrid emerges as one of the best feasible solution for future energy demand while considering zero carbon emission, fossil fuel independency, and enhanced reliability. In this paper, optimization and implementation of institutional based sustainable microgrid are discussed based on cost analysis, carbon emission, and availability of energy resources. Various microgrid topologies are considered for addressing the most ideal solution. The metrological data such as irradiance is acquired from solar satellite data of NASA (National Aero Space Agency) while the data for wind speed is taken from synergy enviro engineer's site. HOMER ® simulation tool is used for modelling and optimization purpose.

This paper proposes an effective method for Congestion Management by identifying the optimal location of TCSC in a restructured power system. TCSC serves as a powerful tool in increasing overall transmission capability of line, improvement of voltage profile and reduction of active power loss of transmission line. As the power flow pattern in restructured power system is difficult to predict, management of congestion is a complicated job. In this paper, it is suggested to find the set of lines on which TCSC can be placed to solve congestion occurred in a line before the actual occurrence of congestion in the network. An algorithm of proposed methodology is given to define the procedure of congestion management. Feasibility of the method is tested on Delhi 33-bus network and results are compared with the paper based on the same network.
