نویسنده
چکیده
in our present paper, we present the effectiveness of the controller's electrical power f low Universal (unif ied power f low controller UPFC) w ith the choice of a control strategy. To evaluate the performance and robustness of the system, w e proposed a hybrid control combining the concept of neural networks with conventional regulators vis-à-vis the changes in characteristics of the transmission line in order to improve the stability of the electrical power network.

However, due to high capital investment, it is necessary to locate these controllers optimally in the power system. FACTS...
متن کاملPower Swings Damping Improvement with STATCOM and SMES Based on the Direct Lyapunov Method
In this paper a comprehensive approach is presented to improve power swings damping based on direct Lyapunov method. The approach combines superconducting magnetic energy storage (SMES) system with static synchronous compensator (STATCOM). Considering the energy absorption/injection ability of SMES, in transient states the combination exchanges both active and reactive powers with power system....

The UPFC can provide simultaneous control of all basic power system parameters ( transmission voltage, impedance and phase angle). The controller can fulfill functions of reactive shunt compensation, series compensation and phase shifting meeting multiple control objectives. From a functional perspective, the objectives are met by applying a boosting transformer injected voltage and a exciting ...
متن کاملA New Strategy for Simultaneous Compensation of Instantaneous Reactive Power and Harmonics of Non-Linear Loads (RESEARCH NOTE)
This paper presents a new control method for simultaneous compensation of instantaneous reactive power and current harmonics by parallel active filters (PAFs). Reference compensating currents of PAF are calculated using the subtraction of instantaneous power from its average value. In this way, it is possible omitting high/low pass filter(s) from the control circuit of PAF, which usually result...
