This book presents a systematic study consisting of modeling, simulation, and optimization of dynamic operations of energy supply networks with distributed generation (DG) and battery storage systems (BSSs). Based on complex power flow models, different optimization problems are mathematically formulated and solved. In addition, novel mathematical models and a new combined problem formulation for active-reactive optimal power flow (A-R-OPF) in passive distribution networks (PDNs) (without DG units and BSSs) and active distribution networks (ADNs) (with DG units and BSSs) are studied....
