The response time and the maximum overload rate of redox flow battery are verified as 350 /spl mu/s and 4.6 times. These systems are advantageous for power control under wide frequency band which covers from spinning reserve to economic load dispatching, and also used for leveling load and maintaining power quality. The instantaneous controls using these systems are effective for dynamic stability, flicker, voltage dip and charging/discharging regenerative power of electric railways. The authors clarify the chemical reactive characteristics of the redox flow battery physically and the effect of secondary control utilizing characteristics of quick response and overload capability of the redox flow battery by dynamic simulation. The battery efficiency increases when the cycle period of charging/discharging becomes shorter. The comprehension about these performances can be used to determine the optimum rechargeable battery system configuration for each use of end users.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.

It is, by nature, an element complex by itself. Therefore, a detailed model of this component is needed to analyze its behaviour under different operation conditions and its influence of the rest of the system. In this state space model developed in the time domain, novel algorithms are used for the representation of nonlinear phenomena of magnetic saturation and hysteresis. In addition, the model can incorporate any number of damper windings and higher harmonic terms in the time-varying inductance matrix. The dynamics of the synchronous machine are represented by a set of ordinary differential equations (ODEs) and solved numerically with the fourth order Runge-Kutta integration method. The synchronous machine is analyzed under balanced and unbalanced operation conditions. Fast periodic steady state solutions are obtained with the application of a Newton Raphson method, for the acceleration of the machine's state variables to the limit cycle. The potential of the Newton methods for achieving efficient time domain solutions of the synchronous machine model is demonstrated.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.

The optimal PMU placement (OPP) problem is, in general, expressed as a combinatorial optimization problem subjected to the observability constraints of the studied power system, which consumes much time to solve. Three approaches, in this paper, are proposed aiming at reducing computational burden in OPP problems. First, a modified simulated annealing (MSA) method, is proposed. The conventional simulated annealing method is slightly modified in setting the initial temperature and in cooling procedure to consider the current state of solution sets. Second, a direct combination (DC) method is suggested using a simple but very effective heuristic rule. When selecting test and neighboring solution sets, this heuristic rule is used to select most effective sets in the observability sense. And the last one is tabu search (TS) method, in which the heuristic rule used in DC method is also used to reduce the searching spaces effectively. Suggested optimization methods are applied, in this paper, to solve OPP problems in IEEE 14, 30 and 57 bus systems. The simulation results show that the proposed methods can find the optimal solutions in an efficient manner.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.
