Challenges facing fuel cell hybrid vehicles is in implementing a control strategy to find the optimal split of power between the different power sources. This paper proposes a mathematical model of power flow in such vehicles taking into consideration power train losses. Linear programming locates the global optimum indicating the finest synchronization among power units in an attempt to lower ...

The Static Synchronous Series Compensator (SSSC) is one of the powerful Flexible AC Transmission System (FACTS) controller recognized for power flow, power oscillation damping and improving transient stability. This paper proposes controller that is a combination of Fuzzy Logic Power Oscillations Damping (FLPOD) controller with Proportional and Integral Power Flow (PIPF) controller for SSSC to ...

–Low frequency electromechanical oscillations are inevitable characteristics of power systems and they greatly affect the transmission line transfer capability and power system stability. Traditionally, power system stabilizers (PSS) are being used to damp these oscillations. Unified Power Flow Controller (UPFC) is a well-known FACTS device that can control power flow in transmission lines. It ...

This paper endeavors to apply a novel intelligent damping controller (NIDC) for the static synchronous compensator (STATCOM) to reduce the power fluctuations, voltage support and damping in a hybrid power multi-system. In this paper, we discuss the integration of an offshore wind farm (OWF) and a seashore wave power farm (SWPF) via a high-voltage, alternating current (HVAC) electric power trans...

Hybrid vehicle fuel economy and drive quality are coupled through the “Energy Management” controller that regulates power flow among the various energy sources and sinks. This paper studies energy management controllers designed using Shortest Path Stochastic Dynamic Programming (SP-SDP), a stochastic optimal control design method which can respect constraints on drivetrain activity while minim...

This paper develops a supervisory level power flow suboptimal controller for a hybrid electric vehicle. The power flow model has two modes of operation determined by whether or not the electric motor is motoring or generating. The solution to the hybrid optimal control problem uses the recently developed embedding technique which places the original problem into a parameterized family of proble...
