| description | The secondary level control of stand-alone distributed energy systems requires accurate online state information for
effective coordination of its components. State estimation is possible through several techniques depending on the
system's architecture and control philosophy. A conceptual design of an online state estimation system to provide
nodal autonomy on DC systems is presented. The proposed estimation system uses local measurements - at each node
- to obtain an aggregation of the system's state required for nodal self-control without the need for external
communication with other nodes or a central controller. The recursive least-squares technique is used in conjunction
with stigmergic collaboration to implement the state estimation system. Numerical results are obtained using
a Matlab/Simulink model and experimentally validated in a laboratory setting. Results indicate that the proposed
system provides accurate estimation and fast updating during both quasi-static and transient states. |
