چکیده
Electric grid is vulnerable to power imbalance and inertia the grid's response overcome such disturbance. Augmentation of electronic converter based renewable energy technologies like Photovoltaic Generators (PVG) batteries in utility significantly reduces inertia. Inertia degradation indicated by sharp Rate Change Frequency (ROCOF) events due any component failure or imbalance. Fixed gain feedback Proportional Integral Derivative (PID) control insufficient deal with varying ROCOF events. This work proposes Sliding Mode (SM) robust droop scheme assisted Artificial Neural Network (ANN) algorithm for an islanded PVG integrated microgrid. Droop governed swing equation that uses Maximum Power Point (MPP) forecasted ANN. ANN forecast compared optimized Gaussian process regression on mean squared error speed training as key performance indicator. The algorithms are trained validated climate dataset Islamabad, Pakistan. SM various PID settings qualified most suitable against variable source, load scenarios. Finally, significance accurate MPP established comparing deterministic forecaster a microgrid case study.

Artificial Neural Network Based Droop-Control Technique for Accurate Power Sharing in an Islanded Microgrid
In an islanded microgrid, while considering the complex nature of line impedance, the generalized droop control fails to share the actual real/reactive power between the distributed generation (DG) units. To overcome this power sharing issue, in this paper a new approach based on feed forward neural network (FFNN) is proposed. Also, the proposed FFNN based droop control method simultaneously co...
متن کاملAnalysis of droop control method in an autonomous microgrid
In this paper an analytical approach is conducted to evaluate the droop control method in an islanding microgrid. Droop control is the key solution for sharing the demand power between generators in autonomous microgrids where there is no support from the electricity distribution grid. In the paper, three important load types are investigated to verify the droop control performance. First, coup...

A Novel Hybrid Droop-Isochronous Control Strategy for Microgrid Management
The droop control strategy is the most common approach for microgrids control but its application is limited due to frequency deviation following a load change. Complementary control strategy has then been proposed to solve the problem using a communication network. However, under this strategy, regular loads profile produces a continuous change of output power of all distributed generators (DG...
