We present our study of a real-time monitoring methodology of pressure-volume (PV) in-vivo signals generated by our implantable RF telemetry system, where the dual PV sensor is implanted in a heart of a freely moving animal subject. I. THE STUDY OVERVIEW Real-time left ventricular (LV) pressure-volume (PV) loops are one of the main indicators of the myocardium health in animals and humans. Accu...

Because of their low impact on environment, PV/wind hybrid systems which use fuel cells (FCs) as the energy storage device are one of the most promising renewable energy sources. In such systems, optimum configuration (sizing) plays an important role for decreasing the system cost. In this paper, PV/wind/FC system is modeled and a hybrid metaheuristic technique based on chaotic search (CS), har...

Four simulation sub-models of four main parts; namely, photovoltaic/thermal (PV/T) collector, silica gel dehumidification unit, living space and air conditioning system, have been developed for a detailed transient simulation model for a hybrid PV/T solar air heating system for regenerating silica gel in air conditioning room.

This paper deals with the design and analysis of standalone solar PV based boost converter with P& O (Perturb and Observe) MPPT (Maximum Power Point Tracking) Techniques. An intermediate converter can therefore increase efficiency by matching the PV system to the load and by operating the solar cell arrays at their maximum power point. MPPT (Maximum Power Point Tracking) controller is used for ...

Demand-side energy management systems (EMSs) are expected to be used as a method for further balancing the supply and demand of power systems with high levels of renewable energy generation, such as photovoltaic (PV) power. Energy demand and solar radiation must be predicted to realize the optimal operation scheduling of demand-side appliances by a home energy management system (HEMS), includin...

This paper proposes a decentralized stand-alone photovoltaic (PV) system, which presents a set of advantages when compared to conventional stand-alone PV system. In the proposed system, the generated energy by the PV arrays is processed by multi-string MPPT step-up converters, which assure a maximum utilization of this energy. The storage system is designed in a decentralized configuration, ena...

Maximum power point tracking algorithm is widely implemented in photovoltaic system to maximize the PV array output power. In general, Perturb and Observe (P&O) is simple thus being selected to continuously track the array maximum power point (MPP). Under uniform solar irradiance, PV array characteristic is non-linear and consisting only one MPP along the functional operating voltage. However, ...

This paper focuses on the grid-connected photovoltaic (PV) systems and their impact on the voltage stability of the power system. The modeling of the PV systems for the voltage stability analysis is presented. The impact of a large penetration of PV generation on the voltage stability is examined through numerical simulations conducted on the IEEJ West 10-machine test system. Several of interes...

This paper presents the simulation and analysis of maximum power point tracking (MPPT) control with modified firefly algorithm (MFA) for photovoltaic (PV) system. The availability of solar energy varies widely with ambient temperature and different atmospheric conditions and hence the maximum power point (MPP) of PV system is not stable. Therefore, a MPPT controller is needed to operate the PV ...
