A large format lithium-ion battery stack emergency power system is designed for electric-propelled vehicles. The large format lithium-ion battery stacks are chosen for their high energy density, modularity, and ready availability. To increase their output power rating, many battery stacks can be connected in series and parallel in an enclosure. We propose to design and develop an intelligent battery management system (BMS) with high-efficiency active cell balancing technology and self-learning battery state of charge (SOC) estimation for the lithium-ion battery. The proposed active cell balancing technology will lead to longer endurances and lengthens the lifetime of the battery for underwater applications. Besides, the 2kWh battery stack module with BMS system is scalable and swappable to provide higher power capacity and increase flexibility in usage. The intelligent lithium-ion battery stack power system developed has high potential for commercialization and will drive academic knowledge and applied research works using backup or main power supply in electric vehicles and environmental surveying.

ASSESSMENT OF TRANSFER CAPABILITY CONSIDERING RISK AND RELIABILITY COST/WORTH IN DYNAMIC AND STATIC SYSTEM CASCADING COLLAPSES.
In a restructured power system, it is important to determine realistic value of Available Transfer Capability (ATC) since this information will be used as a reference by the Independent System Operator (ISO) towards the finest decision making in congestion management especially pertaining to system security and effective electricity market. ATC is the additional amount of power that can be transferred between two areas without jeopardizing the system security and reliability. The determination of ATC must accommodate a certain amount of Transmission Reliability Margin (TRM) vital for resolving between uncertain system securities and maximizing the power transfer. In this thesis, a stochastic framework has been established for ATC and TRM determination by considering uncertainties in hourly peak loads, transmission failures and system cascading collapse. The events of worldwide major blackouts that occurred recently have emphasized on the importance of cascading collapse consideration in determining power transfer capability. The proposed research methodology involved developing an algorithm commenced with a fault occurrence and then followed by the propagation of power system component tripping events which is defined as the system cascading collapse. In this thesis, both static and dynamic operating conditions in a power system are considered in the analysis of system cascading collapse. The assessment of static system cascading collapse is performed wherein its cascaded violation depends on the violation of transmission line limit. On the other hand, the dynamic system cascading collapse is performed by inspecting the violation of generator rotor angle limit and frequency limit starting from the dynamic response of critical clearing time until the final transient stability simulation time. In particular, bootstrap technique is used to generate uncertainties of system parameters comprising with the chronological hourly peak loads, transmission line failures and system cascading collapse. The bootstrap technique is done by replicating the inherent information in order to produce new information considering various levels of system uncertainties. This thesis also introduces on the assessments of risk and reliability cost/worth based Customer Interruption Cost in relation to each case of system cascading collapse. The performance and effectiveness of the proposed techniques were evaluated through the comparison of TRM, ATC, RC and CICC results associated with the static and dynamic system cascading collapses. The results have proven that a large value of TRM is obtained based on the combined uncertainty of chronological hourly peak loads, transmission line outages and system cascading collapse. This signifies that the uncertain tripping events of exposed generator together with exposed transmission lines occurred in the system cascading collapse ultimately will cause to a considerable impact to the TRM and ATC determinations. On top of that, the results of customer interruption cost also have proven that the uncertainty of system cascading collapse should not be ignored from the TRM determination.
