The modern virtual power plant (VPP) concept is introduced to control the proliferated penetration of distributed generation (DG), energy storage elements and controllable loads. This book utilizes the VPP concept for managing the electrical energy in the power delivery networks. The work presented in this book can be grouped into three phases; the first phase includes the studies concerned with the optimal sizing and siting of DG units. The second phase aims to support the renewable based DG units operation via the optimal sizing of the energy storage elements. While, the third phase...
