A novel market based Distribution System controller for active distribution networks

The high growth trend characterizing the Distributed Generation (DG) diffusion in traditional radial structure MV networks leads Distribution System Operators (DSOs) to face, and rapidly solve, some technical, management and commercial issues which may limit the diffusion of DG plants. In the next future DSOs will be called to adopt innovative network control architectures, communication channels and marketplaces in order to coordinate the operation and the management of their electrical systems. The paper presents a new scenario, based on a local price signal theory applied to the distribution network context. A pricing system, computed at each node both for active and reactive energy, may be an efficient way to solve power system management, operation and planning, meeting all the distribution network operational constraints.
