Abstract

Conventional grid-tied single phase inverters of renewable power generators (solar PV systems typical) have limited reactive power compensation capability and do not have active power control. This paper presents a novel control strategy which provides active power control with reactive power compensation for a DC/AC inverter connected to a single-phase AC grid, which supplies electricity to local loads. By sampling the instantaneous current on the grid at the local load side, which represents the domestic load current, an orthogonal signal is constructed using second order generalised integrator. The active and reactive current of the local loads are then rapidly detached from the orthogonal signal through specific trigonometric calculation. The reference current for the inverter output are produced by combining the active current and the reactive current which is detached from the domestic load current. Comparing the reference current with the inverter output current generates the PWM signals which are used to control the IGBT devices of the inverter bridge with capacitive impedance output to achieve domestic reactive compensation for inductive loads. The output current remarkably improves the load capacity of the grid and reduces the demand of reactive power from the gerid.
