Seamless Transfer

Effective execution of business processes also requires the provisioning of relevant knowledge to workers in various business contexts. Knowledge flow automation aims to enable seamless transfer of knowledge by supporting the capture and sharing of organizational knowledge related to business processes. Given the strong correlation between the flow of work and the flow of knowledge, workflow systems are a natural platform for supporting knowledge flow. However, existing workflow technology does not yet provide the needed mechanisms suitable for supporting knowledge flow. This chapter presents an overview of different types of workflow-based knowledge management systems that provide knowledge workers with the required knowledge while supporting the flow of work. In addition, a new perspective is presented on extending workflows to support knowledge transfer processes by introducing the concept of “knowledge workflows” and outline future research directions in this area.

In this paper, we propose a voltage control technique for the seamless transfer algorithm of a microgrid inverter. When the microgrid inverter is switched from grid-connected mode to standalone operation mode, an output voltage transient may occur, and adversely affect the load. To solve this, seamless transfer algorithms that complete mode switching within 4 ms have been studied. However, previous control techniques have very complex structures. In this study, we find the cause of the voltage transient occurring in the mode conversion, through state average modeling of the inverter. Subsequently, we propose a feed-forward compensator for seamless transfer. The cause of the voltage transient is removed by the compensation, and smooth mode switching is achieved. The proposed controller is verified by Powersim (PSIM) simulations.
