Talk Title: Cooperative Output Regulation and its Application in Power Sharing Control of Microgrid

Abstract: In this talk, we present a distributed observer control framework for the cooperative output regulation problem of leader-follower multi-agent systems. With the aid of certainty equivalence principle, it is shown that the cooperative output regulation problem can be solved by a distributed controller composed of a distributed observer of the leader system and a centralized controller of the follower systems. As an application, we further show that the power sharing control problem of a grid-connected AC microgrid can be reformulated and hence solved as the cooperative output regulation problem of an interconnected leader-follower multi-agent system. It is interesting to see that the proposed design is able to handle microgrids where the system parameters of the dispatchable distributed generators are subject to arbitrarily large uncertainties.

Talk Title: Cyber-Physical Security in Remote State Estimation

Abstract: Cyber-Physical Systems (CPS) have attracted considerable interest from both academic and industrial communities in the past few years. Using wireless sensors for remote state estimation is a key component in CPS, and have advantages such as low cost, easy installation, and self-power. However, due to the inherent open characteristics of wireless communication, and the increasing penetration of CPS to safety-critical infrastructures of the society, cyber-physical security issues arise naturally and are of fundamental importance to ensure the safe operation of CPS. In this talk, our recent results about the cyber-physical security in remote state estimation will be introduced.

Talk Title: Multi-hop Sensor Network Scheduling for Remote Estimation

Abstract: In this talk, we consider a design problem of how a group of wireless sensors are selected and scheduled to transmit data efficiently over a multi-hop network subject to energy considerations, when the sensors are observing multiple independent discrete-time linear systems. Each time a set of sensors are selected to transmit their measurements towards a remote estimator. We formulate an optimization problem, minimizing a linear combination of the averaged estimation error and the averaged transmission energy consumption to obtain suitable network scheduling and estimation algorithms. Necessary conditions for network control optimality are derived so that the problem can be

transformed into a Markov decision process problem. We show that under some conditions there exists a periodic network schedule and how it can be computed numerically. Efficient algorithms to obtain suboptimal schedules are proposed to reduce the computational complexity of the original optimization problem.

Talk Title: Optimal Operation of Power Distribution and Consumption System: Cyber-Physical-Social System Perspective

Abstract: Ubiquitous Internet of things (IoT) and Power Distribution and Consumption System (PDCS) are deeply integrated to form a Cyber-Physical-Social System (CPSS). In this presentation, the optimal operation of the IoT-based PDCS is presented from the perspective of CPSS. First, the participants of PDCS is analyzed, including their attributes of the cyber field, physical filed, and social field. The relationships and mutual interactions of these participants are also studied. Second, the operation features of IoT-based PDCS are abstracted in the CPSS perspective.In physical filed, the features include the flexibility of nodes, network, and functions. In cyber filed, the uncertainty of ubiquitous sensing, edge computing, and cybersecurity are essential features. Moreover, new features in the social field include role variability and utility personalization of participants, and diversification of business models. Besides, based on the analysis of the existing studies, five prospective problems are proposed, including feature identification of complex power system, stochastic game theory framework and application with incomplete information, modeling and solving optimization problem with fusion social attributes, scheduling strategy and driving mechanism for edge computing, interactive security mechanism for the IoT-based PDCS, etc. Through the analysis and discussion, we provide analysis and discussion on the multidisciplinary intersection of information, physics and social systems at the theoretical level, and technical support for the construction of ubiquitous power IoT and smart grid at the application level.
