Renewable energy resources have got vital importance in present era as fossil fuel reserves are depleting and their prices are fluctuating drastically. The role of these resources in generation of electricity is inevitable in the developing countries like Pakistan, where energy crisis has become a burning issue due to short fall of electricity. Presently the country is suffering from repeated and shocking black outs. Therefore, the generation of electricity through other than traditional resources has become indispensable. In this research paper an innovative concept has been imparted for the development of Microgrid, based upon locally available renewable energy resources, keeping in view the geographical location of Rachna College of Engineering & Technology (RCET), Gujranwala-Pakistan. These available renewable energy resources have been integrated to function as a single generating unit for forming Microgrid. The comprehensive modelling and simulation of Microgrid has been performed using MATLAB. The objective behind the development of this proto type model of Microgrid is to design a standby power for RCET Library in case of electricity failure from National Grid. Alternative Energy Development Board (AEDB) of Pakistan is looking for viable solution to compensate the National Grid and emergency need of individual sensitive consumers since long. Simulation and implementation of this developed model will really be very helpful for all stake holders of power industry nationally and internationally.

1. Introduction

Microgrid is actually assembly of renewable energy resources able to be operational paralleled or independently from National Grid having capacity up-to Distributed Generation (DG). Microgrid is more modern way for utilizing the available potential of DG, not only in remote area electricity development but also in over coming the short-fall of electricity commercially. Most commonly available renewable energy resources, used for the development of Microgrid, are Solar, Biomass, Micro-hydro, Wind, Fuel Cell etc [1, 2, 3, 4]. Like other developing countries, Pakistan is also suffering from acute energy crisis. The present sources for generation of electricity in Pakistan include Hydro (33%), Natural Gas (35.7%), Oil (28.7%), Coal (0.3%) and Nuclear (2.3%). Despite the massive availability of renewable energy resources, their contribution towards generation of electricity in Pakistan is negligible. The Maximum demand of electricity in Pakistan is about 15,000 MW, whereas supply demand gap is about 3000 – 4000 MW. The renewable resources used in this research work are Solar, Biomass, Micro-hydro and Fuel Cell. Pakistan located in the Sun Belt is ideal for taking advantage of solar energy. The mean global irradiation falling on horizontal surface is about 200–250 watt/ m2 per day, equivalent to about 1500–3000 sun shine hours and 1.9 – 2.3 MWh/ m2 annually [5]. Being an agriculture country, sufficient live stock is available for producing enough animal dung to be utilized in the production of biogas. Following the latest statistical data of AEDB, the available micro-hydro potential in Pakistan is about 2000 MW. Moreover, there is an immense potential to utilize the flow of water in world’s largest canal network, particularly in province of Punjab, Pk [6]. This paper presents a novel approach of Microgrid development in which micro-level energy generation resources are first incorporated with each other to form one generating station controlled by a central unit and simultaneously integrated with National Grid for both way power flow [7]. Conventionally, these DG...
