My Contribution

Modelled the RFB systema and two feeders In GridLAB-D

Proposed Fuzzy multi-objective optimization approach for optimum dispatch of battery storage

Proposed, planned and executed the research project

Project - Battery Energy Storage in Distribution Networks

The Context:

With the Washington Clean Energy Fund, Avista, the local electrical utility in Pullman, WA installed a utility-scale flow battery provided by UniEnergy Technologies (UET) on the Campus of Schweitzer Engineering Labs (SEL).  As part of this project, Washington State University (WSU) participated in the engineering effort by contributing to the modeling and controls effort related to the proper operation of the battery. The Redox Flow Battery (RFB) is a 1 MW, 3.2 MWh utility scale battery storage system commissioned in April 2015 and installed at the premise of Schweitzer Engineering Laboratories (SEL) in Pullman, WA, USA.  

My Role:

Based on my work on battery energy storage which I presented in IEEE PES General Meeting in Denver in July 2015, I was invited by Prof. Anurag Srivastava to work as a visiting research scholar for six months on the on-going project at the Washington State University (WSU), Pullman, USA. I was assigned the task of preparing the detailed three-phase model of the two Pullman feeders with the Vanadium Redox Flow Battery connected to these feeders. The 1 MW, 3.2 MWh battery energy system was in two modules. I was expected to extract the feeder data from the SynerGEE database, process and format the same in GridLAB-D and prepare the GLM files to run the time-series power flow simulations including the RFB. I had developed the code modules for each of the above tasks in VB script and GridLAB-D. The feeder model was then validated with the benchmark values obtained from SynerGEE.

Project Outcome:

torage which I presented in IEEE PES General Meeting in Denver in July 2015, I was selected by Prof. Anurag Srivastava to work as a visiting research scholar for six months on

  1. Developed the code modules to extract the feeder data from the SynerGEE database, format it and prepare the GLM files for GridLAB-D
  2. Performed time-series power flow simulations in GridLAB-D and validated the feeder models including the RFB modules
  3. Developed a Fuzzy multi-objective optimization algorithm to plan the day-ahead dispatch of the battery energy storage system to optimize the daily operations of the two Pullman feeders
  4. The project effort and results are partially published in the following three publications:
