I. Introduction
With the robust growth in the economy, the India introduces new energy policy to tackle the growing energy deficit. This policy mainly focused on Distributed Generation (DG) from the renewable energy resources like solar, wind etc, which provides clean sustainable environment, but the energy production from these resources creates reliability issues which prevent their large scale installation [1]. The smart grid provides effective solution for this problem by utilizing its smart infrastructure. The smart grid consists of demand response, energy management and smart meters which help to integrate renewable energy resources without compromising reliability and quality of power [2]. In this case study, the DG based smart grid concept may be implemented in the educational institution established by state government named “I.K Gujral Punjab Technical University, Jalandhar Punjab, India. The solar PV panels used as the renewable energy resources to supply a large proportion of energy demand of university and remaining demand may be directly taken from the grid. With these results the grid dependability is reduced and at same time the cost of energy is also decreases significantly. The proposal of solar panels installation is under the Indian government roof top scheme and various subsidies are also offered by government for installation. For optimization and simulation of this concept the Homer software is used. The Homer stands for Hybrid Optimization Model for Electric Renewable developed by National renewable energy laboratory is popular and effective program that is used in various studies regarding the renewable energy and DG [3]. The data required for the homer simulation is taken from the 11kV substation built within the university campus.
