Distributed Power generation Systems (DPGSs) integrate different power plants in to a unit. DPGSs based on renewable energy sources experience a large development worldwide. The excessive use of power electronics and nonlinear loads lead to power quality problems. Effects of poor power quality like sag, swell, distortion in waveform, harmonics, reactive power generation has affected both grid as well as utility sectors. The control of distributed generation systems should be improved to meet the requirements for grid interconnection. In this thesis, Photo Voltaic (PV) panel, Fuel Stack & Wind Energy system are integrated to the three phase four wire distribution system. Renewable energy resources (RES) are connected to the grid through a grid interfacing inverter for power quality improvement. Here the control is done by the grid interfacing inverter using PI controller and PWM technique. The grid interfacing inverter can act as an active shunt filter where it can transfer active power to the grid and can mitigate the load current harmonics and supply the load reactive power demand. The source side power factor is improved and voltage sag is eliminated. Total Harmonic Distortion of the grid connected system is analysed. The analysis is used to predict the behaviour of grid connected distributed power generation systems.

“…A similar approach in which a shunt active filter acts as active conductance to damp out the harmonics in distribution network is proposed in [4]. In [5], a control strategy for renewable interfacing inverter based on -theory is proposed. In this strategy both load and inverter current sensing is required to compensate the load current harmonics.…”

Renewable energy resources (RES) are being increasingly connected in distribution systems utilizing power electronic converters. This paper presents a novel control strategy for achieving maximum benefits from these grid-interfacing inverters when installed in 3-phase 4-wire distribution systems. The inverter is controlled to perform as a multi-function device by incorporating active power filter functionality. The inverter can thus be utilized as: 1) power converter to inject power generated from RES to the grid, and 2) shunt APF to compensate current unbalance, load current harmonics, load reactive power demand and load neutral current. All of these functions may be accomplished either individually or simultaneously. With such a control, the combination of grid-interfacing inverter and the 3-phase 4-wire linear/non-linear unbalanced load at point of common coupling appears as balanced linear load to the grid. This new control concept is demonstrated with extensive MATLAB/Simulink simulation studies and validated through digital signal processor-based laboratory experimental results.Index Terms-Active power filter (APF), distributed generation (DG), distribution system, grid interconnection, power quality (PQ), renewable energy.

Power electronics plays an important role in controlling the grid-connected renewable energy sources. This paper presents a novel adaptive neuro-fuzzy control approach for the renewable interfacing inverter. The main objective is to achieve smooth bidirectional power flow and nonlinear unbalanced load compensation simultaneously, where the conventional proportional-integral controller may fail due to the rapid change in the dynamics of the highly nonlinear system. The combined capability of neuro-fuzzy controller in handling the uncertainties and learning from the processes is proved to be advantageous while controlling the inverter under fluctuating operating conditions. The inverter is actively controlled to compensate the harmonics, reactive power, and the current imbalance of a three-phase four-wire (3P4W) nonlinear load with generated renewable power injection into the grid simultaneously. This enables the grid to always supply/absorb a balanced set of fundamental currents at unity power factor even in the presence of the 3P4W nonlinear unbalanced load at the point of common coupling. The proposed system is developed and simulated in MATLAB/SimPowerSystem environment under different operating conditions. The digital signal processing and control engineering-based laboratory experimental results are also provided to validate the proposed control approach.
