    Modern world is witnessing rapid changes due to changing demographic, scientific and climatic conditions. This is reflected equally in the energy utility landscape as well. The political and economic dynamics in favor of carbon neutral measures, wide legislations by government bodies for accommodating distributed renewable energy sources is gradually abating the natural monopoly the utilities once used to enjoy; thus opening up new possibilities for the energy management. In a bid to survive and stay afloat in the era of hyper-competition, the utility and transmission system operators (TSOs) are focusing on curtailing the operational expenditures (OPEX), optimizing the capital expenses (CAPEX) and still trying to run the business profitable. The efforts carried out in the process has also to be sustainable so that it does not die during or after major technological or economic reforms.

    India stands a special place due to its demographic dividend, quest for power and connectivity and massive technological need to cater to the common mass. To overcome different challenges, indigenous technology push plays a vital role. In this direction several government organizations and initiatives have become instrumental to make socio-economic impact.

    At the same time, the emergence of fourth industrial revolution is shifting focus towards digitalization, cloud computing, big data analytics, internet of things and related topics. The lecture will discuss on some of the challenges related to the convergence of power and automation sector. The challenges in this field is enormous and so are the opportunities. The future prospects of connected things in a power system and the role of automation in improving the quality of life in the context of smart cities will be discussed in the lecture.

    Cyber-Physical Systems (CPS) are engineered systems resulting from a seamless integration between physical processes and cyber technologies such as communication networks and computational hardware. This tight integration exposes the CPS to a variety of attacks, both on the physical and cyber components, which can result in significant performance degradation. Further, CPS usually consist of multiple agents that collaborate and share information with each other, thus making them vulnerable to privacy breach and leakage of confidential data. This talk will focus on the need, design and analysis of security and privacy mechanisms in CPS.

    In the first part of the talk, we will present a security problem for real-time resource- constrained autonomous systems (for example, a UAV), which can reserve only limited computational resources and time for security and control purposes. In such scenarios, the control and security tasks usually compete with each other for limited resources and there exists a trade-off between security and control performance. We characterize the optimal trade-off and identify attack regimes in which the system should prefer control tasks over security tasks, and vice-versa.

    The second part will focus on privacy in cooperative dynamical multi-agent CPS. We present a noise adding differentially private mechanism to preserve the privacy of agents’ state over time, and analyze the effect of the privacy mechanism on the system performance. Next, we show that a fundamental trade-off exists between privacy and cooperation level, and it is beneficial for the agents to reduce cooperation if they want to be more private.
