چکیده
This paper applies a voltage instability monitoring method based on and current measurements from transmission bus PMU the Hellenic Interconnected System using both unstable marginally stable scenarios, derived historical 12 July 2004 blackout of Athens area. The effectiveness, selectivity reliability proposed is clearly demonstrated, allowing its integration into Protection Scheme with direct load shedding. It shown that detection control scheme could have prevented collapse if applied at time event.

Static Synchronous Compensating Voltage Control in Power System Using Flat Adaptive Control
Static Synchronous Compensator (STATCOM) is a FACTS device whose structure is based on a voltage source converter and is installed in parallel to control the voltage of the transmission line in the power system. In this paper, a flat adaptive control system for STATCOM output voltage control is simulated. By linearizing the nonlinear dynamics and changing the system state variables, the control...
متن کاملCompensation of Voltage and Current Harmonics in Hybrid Renewable Energy System Using Coordinated Power Control of RES Inverter
In this paper, an adaptive control strategy is proposed for the inverters of renewable energy source (RES) to simultaneously control the load voltage, grid current and the amount of instantaneous injected power to the grid in the presence of grid voltage distortions and nonlinearity of load current. In the proposed control strategy, the power quality of the local load can be settled based on th...
