DERri Common Reference Model for Distributed Energy Resources—modeling scheme, reference implementations and validation of results
- 147 Downloads
One main issue in current research activities regarding power distribution networks is the grid operation with a high penetration of Distributed Energy Resources (DER), particularly renewable sources from wind, solar or biomass, characterized by intermittent and only partially predictable production. In fact, in order to keep power quality and grid stability in presence of great amount of variable production from renewable sources, a large effort is necessary to control the distributed power generators and/or the energy demand (i.e., loads and storages).
The exchange and reuse of DER dynamic simulation models between different users is very complicated today. In fact, heterogeneous models are used for representing component models, which are normally described for a particular simulation environment, contain different levels of details and are difficult to compare.
In order to improve sharing of simulation models the project partners of the European DERri project have developed a standardized modeling schema and exchange format called Common Reference Model (CRM). This approach and specification is suited to study the DER-grid interactions, in dynamic conditions, under various simulation scenarios and time horizons.
Within this work, rules and procedures for modeling DER components in simulation environments in an implementation independent representation based on the CRM specification are proposed. In addition, some reference implementations are presented which are validated by comparing simulation results in different platforms.
