REACTIVE POWER CONTROL WITH THREE-PHASE INVERTER FOR GRID-CONNECTED PHOTOVOLTAIC SYSTEM - TRƯỜNG ĐẠI HỌC HỒNG ĐỨC

This paper proposes the Finite control set Model Predictive Control (FCS-MPC) with delay compensation for three-phase threelevel T-Type NPC inverter (T-Type NPC) of grid-connected photovoltaic systems (PV). The proposed FCS-MPC controls the objectives: current tracking control, DC-link capacitor vol[r]

In the first section of this chapter Power quality disturbances, such as Voltage sag, Interruption, transient overvoltage, swell, Harmonic issues and voltage imbalance, are Introduced. Statistical voltage sag Indices used for characterization and assessment of power quality a[r]

Abstract — Reactive power plays a significant rule in power system reliability and security. Reactive power is considered as the network constraint in conventional reliability evaluation techniques. The impact of the failures of reactive power<[r]

The configurations with thyristor DC current link AC–AC converter and, respectively, with thyristor cycloconverter seem to be merely of historical interest, as their reactive power drainage and current harmonics content are no longer acceptable in terms of power qu[r]

One special type of PWM, that is nowadays extremely frequently applied, is the so-called ‘voltage space vector modulation’. This PWM method is frequently used in vector controlled drives of so-called ‘voltage-fed’ type, as will be discussed later. Once when the space vectors have been introduced, it[r]
