Abstract: An energy management and optimization system for smart grids is proposed to manage available zonal tools and resources to fulfill the objectives of a decision maker. The present invention is based on an efficient energy management system that monitors and manages the power of a zonal segment of the power system, at a flexible scale while taking into account the nature and characteristics of the zone. The system can be easily integrated with existing single unit and whole system.

Abstract: A general decentralized voltage control scheme is proposed to coordinate the operation of DG, Voltage regulator and Capacitor banks. The present invention is based on placing a Remote Terminal Unit (RTUs) at each distribution generation (DG) and each at line capacitor. These RTUs being coordinated together through communication protocols form a multi-agent system. Novel decentralized system is proposed to estimate the voltage profile change as a result of injecting reactive power at the capacitor bus. Simulation results are presented to show the validity and the effectiveness of the present invention.
