Design and Study of an Intelligently Controlled Power System Deploying AC and DC Power Sources and Transiently Operated AC and DC Loads
Abstract
Design and Study of an Intelligently Controlled Power System Deploying AC and DC Power Sources and Transiently Operated AC and DCAb"stractSince 2010, the UT Arlington Pulsed Power and Energy Laboratory (PPEL) has been performing research to support the US Office"" of Naval Research (ONR) in several power and energy related areas. To date, the research has focused on studying the challenges tha""t will be faced when the Navy attempts to integrate high power, transiently operated, loads into the next generation of naval vessel". These loads will introduce significant variation into the power system~s load profile. They may not always be predictable and ther"efore may have adverse effects on power quality when operated. To mitigate variability, it is proposed thatintelligent energy stora""ge systems be utilized as a buffer within the power system, allowing stiff sources to maintain a steady baseload and acceptable powe""r quality. With the integration of transient loads and energy storage into the power system, many challenges will arise that must be" further studied and better understood prior to deployment. The many challenges involve optimization of the of distributed generatio"n power system architecture, power electronic converter design and control, design of an overarching power systemcontroller, and th""e safe operation of the energy storage. Through previous grant support from ONR, each of these topics has been studied already at va""rying levels of detail, at lower power levels. To date, UTA has assessed the performance and aging of lithium-ion cells for use in h""igh power applications at the cell and module levels, designed a ~10 kW actively controlled hybrid energy storage module and demonst""rated that it can improve the power quality of a power system deploying a gasoline generator and a transient load,designed and demo""nstrated the operation and control of 1000 VDC batteries supplying transient power, demonstrated the integration of a hardware in th""e loop (HIL) platform into a subscale power system testbed, and validated power electronic converter models for deployment in larger" shipboard power systemsimulations. A few of these efforts are still in the finishing stages of completion and it is proposed that funds be obtained in FY18 to complete them as well as leverage experience gained to date in the final installation and control of a ~150 kW distributed generation power system testbed. Funds were obtainedthrough the FY17 DURIP program to procure the majority of the necessary hardware to construct the testbed. The funds requested here will be utilized to procure a few final pieces of equipme"nt, support the laboratory student researchers in FY18, and support NSWC Philadelphia as they stand up a similardistributed generat"ion testbed of their own. UTA will be able to stand up their facility well in advance of NSWC Philadelphia and therefore assist them" in identifying challenges they will face, advancing their knowledge base, and reducing the risk of control and hardware integration" problems that may arise as they come online.
