This paper presents a discussion on architecture-oriented assurance technology in Micro grid. We analyzed the characteristic of Micro grid from evolutional view, and proposed the concept of architecture-oriented assurance technology in Micro grid from the technology evolution and policy evolution. Technology evolution contained Function Evolution, Role Changing Autonomy and Role Coordination. Policy...
A new power delivery strategy is proposed in this paper. It relies on integrating distributed energy resources (DER) to AC distribution networks through a multi-terminal voltage sourced converter (VSC) based DC system. To accomplish this, a new converter topology is designed. This topology integrates both AC and DC networks and is unified for different voltage and power levels. It allows full power...
This paper presents a discussion on the control techniques required for microgrid operation and implements a simple control strategy in a microgrid model realized with Matlab. The modeling and control strategy are kept elementary. This is done in order to use developed model for teaching and student training purpose for power system curriculum in undergraduate courses. The model is helpful in introducing...
The economic evaluation of the microgrids is still challenging. This paper presents a methodology to design the number and capacity for each piece of equipment (e.g. gas engines, batteries, thermal storage tanks) in a microgrid with combined heat and power (CHP) system. In the methodology, annual cost is minimized by considering the partial load efficiency of a gas engine and its scale economy, and...
The paper deals with a microgrid test facility, settled at the CESI RICERCA laboratories, equipped with various distributed energy resources (DERs) and connected to a LV network. The operation of such a microgrid is supervised by a central automatic microgrid management system (MMS). The paper first reports and discusses some experimental results carried out for the assessment of DERs performance...
The benefits of distributed energy resources (DERs) can be exploited by developing cost efficient deployment strategies. System planning based on stipulated reliability criteria leads to robust architectures which can meet the consumers' requirements. This paper presents a method for determining siting, sizing and optimal mix of resources from the available types of DER in a microgrid. The method...
The information exchange and coordinated control of distributed energy resources (DER, i.e., distributed generation, storage, and load) for many different purposes to the benefit of various parties represents a complex problem. The large number of DER devices means that the information exchange approaches, must be scalable, must accommodate a changing variety of communications technologies over time,...
