Abstract: Systems and methods are provided for combined inductive power transfer (IPT) and capacitive power transfer (CPT) to reduce power pulsation in dynamic charging of electric vehicles. Aluminum plates provided between transmitter coils inhibit output power drop, the power pulsation can be reduced, and a constant power profile is provided by operation of CPT system when the receiver is between the IPT coils. As the aluminum plates cover the space between coils, the IPT coils can be separated away from each other by a longer distance compared to conventional segmented coils; therefore, a lesser copper can be used which enhances the cost effectiveness of the provided system. As the respective IPT and CPT system are used alternatively, thus the system's output power can be constant, nearly constant, or effectively constant.

Abstract: Power controllers (e.g., inductive power transfer (IPT) power controllers) and methods of making and using the same are provided. An IPT power controller can be implemented on direct alternating current (AC)-AC converters and can use only current and voltage measurements to produce multi-power level IPT controller and design switching logic. Using Boolean operators (e.g., AND, OR, Not) applied on a resonant current signal, varying positive energy injections (e.g., 1 to 16 pulses), and varying negative energy injections (e.g., 1 to 16 pulses), up to 32 different active states can be designed.

Abstract: Hybrid renewable energy source systems and methods are provided. A hybrid renewable energy source system can include a renewable energy source system (e.g., a photovoltaic (PV) system) in conjunction with an energy storage system (ESS), such as a battery energy storage system (BESS). The hybrid renewable energy source system can include at least one intelligent decentralized controller at the inverter/converter level, feeding a robust coordinated controller, thereby allowing the hybrid renewable energy source system to operate as a unified single power generation unit (PGU).

Abstract: Flexible fuel cell sensors and methods of making and using the same are provided. A fuel cell sensor can be used for the detection of, for example, isopropyl alcohol (IPA), and the working mechanism of the fuel cell sensor can rely on redox reactions. The fuel cell sensor can include a proton exchange membrane (PEM), an anode disposed on a first surface of the PEM, a cathode disposed on a second surface of the PEM opposite from the first surface, and a reference electrode disposed on the first surface of the PEM and spaced apart from the anode.

Abstract: Systems and methods for detecting and/or identifying an attack on a battery management system (BMS) or a battery system. The voltage and/or state of charge (SOC) of the BMS or battery system can be monitored, and one or more datasets can be obtained. A principal component analysis (PCA) based unsupervised k-means approach can be applied on the one or more datasets to monitor for irregularities that indicate an attack.

Abstract: Systems and methods for boosting resiliency of a power distribution network (PDN) are provided. A distributed energy resource (DER) hosting process can be used to boost network resiliency through the use of locally installed DER systems that can be operated, dispatched, and/or controlled as individual power plants. A unique critical infrastructure (CI) ranking scheme can be used to prioritize CIs to be optimally located close to the DER while increasing the DER hosting capacity of the network.

Abstract: Testbeds for battery management systems (BMSs) and/or batteries, as well as methods of using the same, are provided. A testbed can be a control-hardware-in-the-loop (CHIL) testbed and can include a simulation bench including a battery cell simulator, a temperature simulator, and/or a real-time simulator. The simulator bench can further include a programmable power supply, a relay, a resistor, and/or a communication protocol.

Abstract: Systems, methods, and frameworks for distribution grid optimal power flow (D-OPF) are provided, to find the optimal droop and mode settings of smart inverters (SIs). The droop and mode settings of SIs can be found as per the Institute of Electrical and Electronics Engineers (IEEE)-1547 in coordination with the operations of legacy voltage control devices for optimal Volt-VAR control performance. The D-OPF framework can utilize two timescale coordination of control of legacy grid voltage control devices, modes and droop settings of SIs, and active/reactive power dispatch of SIs.

Abstract: Systems and methods for forecasting renewable energy generation using holistic weather and system analysis are provided. Derate factors of energy sources can be considered, along with regional weather variability, site specific weather, and a cross-view of the sky from ground based and/or geo-stationary satellite imaging. The forecast can include short-term forecasting and long-term forecasting.
