The microgrid is a conceptual solution proposed as a plug-and-play interface for various types of renewable generation resources and loads. The high-level technical challenges associated with microgrids include (1) operation modes and transitions that comply with IEEE1547 and (2) controlarchitecture and communication. In Part I, the emphasis is on the design of an electrical controlarchitecture for an offshore oil drilling platform powered by wind generation. Engineering a distributedcontrol system having safety critical features, requiring real-time performance is challenging. In this follow-up article we introduce the communication framework for the microgrid scenario under investigation. In all communication networks, scholastic delays and performance are inherent. The only feasible approach is to put bounds on the random processes, qualitatively define the worst cases, and build the distributedcontrol system to be resilient enough to tolerate those behaviors. This is the approach taken by this paper. We propose a communication architecture, discuss performances requirements of the sub-systems, and layout network solutions meeting those specifications.

Solid-state transformer-based smart transformer (ST) can operate in meshed and hybrid grids, which can increase the hosting capacity of renewables and meanwhile reduce the reinforcements in electric grids. In order to adapt the new paradigm, the system performances of the ST-based meshed and hybrid grids are studied and then an effective energy management system (EMS), which is based on a distributed control architecture, is presented to control the meshed and hybrid grids operating in an intelligent and coordinated way.

However,there is limited sensor feedback due to lack of appropriate *** feedback is required for repeatable actuator movements from macro- down to the *** complicates the design of reliable automation *** this paper,the development of an automated robot-based toolbox for cell injection and handling is presented. This toolbox includes several sensor methods,bridging several orders of magnitude as feedback for automation. A non-linear support vector machine(SVM) is applied for classification of the viability of cells as feedback for quality control.A visual servoing algorithm for position tracking of the injection needle as well as an injection force sensor have been *** automation results and the control system are explained.
