This IEEE PES DLP webinar is organized by IEEE UK and Ireland Power & Energy Society Chapter and hosted by University of Birmingham IEEE Student Branch on 5th May 2022. Dr. Joydeep Mitra was invited to give a presentation on the topic of ‘Use of Energy Storage for Reliability Improvement of Renewable Generation’.

Joydeep Mitra (Ph.D., FIEEE) is MSU Foundation Professor of Electrical Engineering at Michigan State University, East Lansing, Director of the Energy Reliability & Security (ERiSe) Laboratory, and Senior Faculty Associate at the Institute of Public Utilities. Prof. Joydeep Mitra is the recipient of the 2020 Merit Award from the International Society for Probabilistic Methods Applied to Power Systems (PMAPS) and the 2019 IEEE-PES Roy Billinton Power System Reliability Award. He serves as Chair of the IEEE-PES Fellow Evaluation Committee and as an Associate Editor for the IEEE Transactions on Industry Applications.  Prof. Joydeep Mitra has conducted research in power system modeling, analysis, stability, control, planning and simulation, and is known for his contributions to power system reliability analysis and reliability-based planning.

Prof. Mitra firstly introduced the Energy Reliability & Security Lab before starting his presentation. The following presentation consisted of three main sections: 1) Renewable energy outlook; 2) Variable generation and associated challenges of energy storage; 3) Utilization and sizing of the energy storage.

Prof. Mitra started the presentation by describing the growth of renewables in worldwide electric energy production and introduced the contribution of renewable resources of UK and Ireland. Then he developed a mathematical method to determine the amount of storage required to meet a reliability target at a specific load point. This method was further applied into a more complex island-capable micro-grid system with solar generation, and a grid-connected system with wind generation. The reliability metrics and targets, and a method for quantifying the notion of “firming up” an intermittent resource were then discussed. Effects of resource availability and network constraints were also considered within the analysis.  Besides, Prof. Mitra illustrated how to use augmented wind farms in IEEE Reliability Test Systems.

Finally, Prof. Mitra explained how energy storage can be used to improve the reliability of wind energy integrated systems with frequency security constraints and gave corresponding simulation results.
