In this paper, a hybrid controller design for a continuous-time linear time-invariant (LTI) plant is presented. The idea is to simultaneously design the flow and jump maps with the respective sets of the controller, guaranteeing H∞ specifications and decay rate of the plant state of the hybrid closed-loop system. A convex LMI-based design procedure is proposed, generalizing the results in [22].

Flexible ac transmission systems (FACTS) controllers, which can effectively enhance the loadability of the network by controlling the power flows, must be placed optimally due to their high cost. This paper proposes a mixed integer based non-linear programming approach for optimal location of UPFC for system loadability enhancement in competitive electricity markets. The method accounts for ac ...

Abstract:This paper presents the planning of an optimal Energy Management System (EMS) supported by a fuzzy logic Controller (FLC) for a residential grid-connected micro grid with hybrid renewable generation (Wind & Photo Voltaic) and storage system. Modelling hybrid system includes Renewable Energy Sources given at intermittent supply conditions and dynamic energy demand, and to make conceptua...

in this paper, an adaptive rule based controller for an anti-lock regenerative braking system (arbs) of a series hybrid electric bus (sheb) has been proposed. the proposed controller integrates the regenerative braking and wheel anti-lock functions by controlling the electric motor of the hybrid vehicle, without using any conventional mechanical anti-lock braking system. the performance of the ...

The unique capability of the Unified Power Flow Controller in multiple line compensation are integrated into a generalized power flow controller that is able to maintain prescribed and independently controllable, real power and reactive power flow within the line. We demonstrate the proposed technique on a single machine infinite bus system. In this paper, we propose UPFC with PSS design scheme...

Based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. However, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. To resolve this problem, hybridization of the fuel cell and energy storage device...

In large power systems, low frequency electro-mechanical oscillations often follow the electrical disturbances. Generally, power system stabilizers (PSS) are used in conjunction with Automatic Voltage Regulators (AVR) to damp out the oscillations. However, during some operating conditions this device may not produce adequate damping and other effective alterations are needed in addition to PSS....

The hybrid AC-DC microgrid (HMG) architecture has the merits of both DC and AC coupled structures. Microgrids are subject to intermittence when the renewable sources are used. In the HMG, since power fluctuations occur on both subgrids due to varying load and unpredictable power generation from renewable sources, proper voltage and frequency regulation is the critical issue. This article propos...
