Abstract
The penetration of Distributed Energy Resources (DER) at medium and low voltages (MV and LV), both in utility networks and downstream of the meter, is increasing worldwide. Small CHP applications (kW-scale), together with solar photovoltaic (PV) modules, small wind turbines (WTs), other small renewable sources, heat and electricity storage, and flexible loads are expected to play a significant role in future electricity supply. While the application of DERs provides a number of distinct economic and environmental advantages, the control of a potentially huge number of DERs creates a major challenge for operating the network safely and efficiently. This challenge can be addressed by microgrids, organized in a hierarchical way, which aims to coordinate DERs in a consistently more decentralized way. Thus, the control burden on the grid is reduced and DER are allowed to provide their full benefits. Microgrid design and operation demand new skills and technology, while distribution systems containing high DER penetration may require considerable operational control capabilities.
The basic characteristics of the distributed control approach will be presented and the advantages it offers in the operation of Microgrids, DER and LV consumers will be identified. The traditional control approaches based on powerful SCADAs and Centralized/Client Server Architectures, although still efficient for large power stations or Transmission System Control, are not sufficient for the management of large number of DGs or LV consumers. New concepts such as Multi Agent Systems and Service Oriented Architecture, capable to provide the necessary functionalities will be presented. Finally, experiences of real test sites developed in various EU research projects, such as the More Microgrids, EU-Deep, and Smart House/Smart Grids will be demonstrated.
