Milwauke Public Radio (WUWM) interviews with Prof. Nasiri on Microgrids

Microgrids are self-contained local electrical power grids that integrate a combination of energy-generating sources, loads and energy storage. Perfecting microgrids will ensure a source of uninterrupted power. That's why UWM and the Wisconsin Energy Research Consortium are teaming up to build one on campus later this year. Tom Luljak interviews John Bobrowich, executive director, Wisconsin Energy Research Consortium (WERC) in Milwaukee and the Center for Renewable Energy Systems (CRES) in Madison and Adel Nasiri, UWM associate professor of electrical engineering.

Prof. Nasiri was selected as the 2010 Young Engineer of the Year by Engineers and Scientists of Milwaukee (ESM).

Prof. Nasiri was the recipient of the 2010 UWM Graduate School/UWM Foundation Research Award.

Characterization of Energy Storage System for Wind Energy Support  
The objective of this research is to develop an innovative integrated wind and energy storage system to support wind energy to achieve higher penetration in the electric utility grid. Energy storage can play a major role in improving the short-term and long-term dynamics, power dispatchability, and reducing voltage and frequency footprint of the wind energy. The main intellectual merit of this project is to model, simulate, and characterize an integrated system of wind turbine generator hardware and controls with a new utility scale battery. The analysis from the modeling and simulation will be applied and a scaled down model of the system will be built, tested and characterized. The system developed in this project is capable of assisting in mitigating dynamic power intermittency, long term power smoothing and power shifting, regulating voltage, controlling power ramp rate, and frequency droop control.

Grid Frequency Support and Inertia Emulation Using Distributed Energy Storage Systems for Wind Turbines 
In order to sustainably increase the penetration of the renewable energy sources, they need to provide electromechanical stability support for the electric grid. Currently, wind energy installations do not provide any frequency and inertia support for the utility grid as the conventional power generators do. Utility companies are requesting that the wind farms participate in grid voltage and frequency support. In this project, we are proposing to use turbine level energy storage systems (ultracapacitors and batteries) to provide frequency and inertia support. The output power of the farm and grid frequency are monitored to adjust the storage charging/discharging patterns at the turbine level in order to achieve frequency and inertia support. For the last 3-4 years, the PI has been conducting research on integrating different types of energy devices with wind turbines. The goal has been to perform power smoothing and power ramp control for the wind farms. The wind turbine topology to perform long and short term wind energy support has been patented by the PI through UWM Research Foundation. The same topology can be used for inertia emulation and frequency support. The objective of this project is to conduct the initial study and prove the viability of our patented topology for inertia and frequency support.

Lithium-Ion Ultracapacitors integrated with Wind Turbines Power Conversion Systems to Extend Operating Life and Improve Output Power Quality  
In this project, we propose to utilize Lithium-Ion Capacitor (LIC) on the DC bus of a full four-quadrant power conversion system utilizing an algorithm to (i) pull mechanical power surges off the drivetrain and into the LIC for dispatch to the grid and (ii) support the grid and protect the turbine during power system transients. The immediate benefit of the proposed topology is less mechanical wear, higher efficiency and lower cost as well as improving power system transient stability. The proposed topology requires that the target wind turbine have double conversion converter. This type of wind turbine system is experiencing a large growth due to needs for more controllable systems. The example systems include GE 2.5MW, Siemens 2.3 and 3.6MW, ABB 0.5MW through 5MW, Clipper 2.5MW and majority of new small wind turbines. The utilized energy storage device is an LIC manufactured by JM Energy Corporation, a subsidiary of JSR Corporation. The main objective of this project to develop, model, design, optimize, build a scaled down model, and characterize an integrated system of LIC energy storage and power conversion system that provides extended mechanical operating life, higher power efficiency and improved quality of output energy and power.
