Control and protection in low voltage distribution grid

My book is about the protection and control in the CIGRE low voltage distribution grid and the networks like this in case of large scale renewable energy integration. As the stochastic nature wind and solar power creates problems of voltage and power oscillations in the main grid and also RE integration presents problems in the protection of the networks. Some of these problems have been solved in this book. Also the mitigation of the balanced and unbalanced voltage sags have been presented in this book. The issues of the islanding and reconnection have also been discussed here and the constancy of the voltage and the frequency in the islanded Micro Grid (MG) has also been maintained by using STATCOM controllers
