Abstract

Talk: Smart Grid Integration of Renewable Energy Sources and Energy Storage Systems for a Self-Sufficient and Sustainable Campus: A Case Study of IIT Roorkee

The transition to future grids powered by decentralized renewable energy sources is increasingly recognised as a crucial step towards achieving long-term economic and environmental sustainability. To validate and demonstrate the effectiveness of integrating decentralized renewable energy sources in weak distribution networks, the IIT Roorkee distribution system has been chosen as a case study. This approach aims to validate the potential of the system in improving the performance and reliability of grids that are prone to voltage fluctuations, power outages, and other challenges. At first, the IIT Roorkee distribution network was without solar and entirely depends on a conventional grid system. To make a self-reliant distribution network, the IIT Roorkee has been performing pioneering work in recent years to develop an eco-friendly campus utilising renewable resources. The IIT Roorkee has installed solar PV systems in 36 different sites across campus with a total amount of 2.8 MW of solar power capacity. However, as solar installations proliferate, integration at the distribution level will be accompanied with significant challenges in the distribution network. These issues include overvoltage fluctuations, the unintended trip of solar inverters, the inability to use renewable energy during power outages, and additional issues that might occur during large- scale integration of renewable energy sources, such as peak energy deficit, system instability, etc. Furthermore, whenever power outages happen the PV inverters are incapable to operate in islanding mode due to the absence of a strong grid which affects the critical and emergency loads. To address the aforementioned problem, smart grid technology must be integrated into the existing grid infrastructure. The ultimate goal is to build a self-sufficient, zero-emission green campus. Furthermore, the implementation of the energy storage system would allow for increased renewable energy utilisation while simultaneously lowering the carbon impact. The literature stresses the perspective of the system from the component level with parameters distant from reality or a strong source. The ADMIRE lab is well-equipped for this, including RTDS, Opal-RT, and FPGA controllers. It aids in the real-time study of weak distribution networks with solar integration, as well as the development and implementation of a monitoring system. This focuses on real-time simulation and analysis by collecting real-time data from each bus in a network.

An advanced storage management algorithm is designed to optimise the selection, sizing, and placement of distributed storage systems while taking network configuration, probabilistic load variation, and solar generation into account in order to improve the efficacy and reliability of the distribution network with the least amount of investment. Prior to the actual deployment of BESS, a feasibility study and analysis will be carried out in the real distribution network utilising Power Hardware in Loop (PHIL) simulation. To perform the PHIL, the impact of the best-chosen BESS on the distribution network and vice versa is examined using inputs from optimization approaches. The PHIL study system consists of a reduced BESS prototype connected to the power amplifier. This is in turn connected to a weak distribution network simulated in real-time by considering inputs from various buses in the actual network. The PHIL study would help to visualise the actual performance of the BESS in the high PV integrated weak distribution network. Furthermore, the performance of the control system and its stability in real-time can be studied under various practical conditions.
