چکیده

This paper proposes coordinated design of wide-area damping controller (WADC) in the presence renewable energy resources a large-scale power system. To tackle with constant and time-varying delays system, robust criterion based on H∞ has been used for WADC design. By using an auxiliary function Lyapunov function, conservatism linear inequality matrix (LMI) is reduced, such that larger delay margin feasibility region obtained delays. The wind farms here are composed doubly-fed induction generator (DFIG) squirrel-cage (SCIG), which connected to common bus photovoltaic (PV) system by unified flow (UPFC). Then, units integrated 10 16-machine systems. Afterwards, identifying oscillating modes, carried out rotor-side-converter (RSC) DFIG, DC/AC converter PV units, shunt (SHC) UPFC, stabilizer (PSS). Different scenarios operating conditions considered evaluate performance proposed approach. simulations analysis toolbox (PSAT) programming MATLAB demonstrate effectiveness conducted method.

Optimal Power Allocation for Renewable Energy Source

Battery powered transmitters face energy constraint, replenishing their energy by a renewable energy source (like solar or wind power) can lead to longer lifetime. We consider here the problem of finding the optimal power allocation under random channel conditions for a wireless transmitter, such that rate of information transfer is maximized. Here a rechargeable battery, which is periodically ...

Using Dynamic Thermal Rating and Energy Storage Systems Technologies Simultaneously for Optimal Integration and Utilization of Renewable Energy Sources

Nowadays, optimal integration and utilization of renewable energy sources (RES) are of the most challenging issues in power systems. The wind and solar generation units' maximum production may or may not occur at peak consumption times resulting in non-optimal utilization of these resources. As a solution to this problem, energy storage systems (ESS) are embedded in networks. However, the power...
