The smart grid has been using more and more power electronic devices as an improvement to the current electrical power system along with plug-and-play integration of alternating sources of power. It has adopted the latest wired/wireless technologies incorporated into electric devices for timely information flow, control and on-demand interaction with customers. So, smart grid is reliable, efficient, and user as well as environment friendly. The grid keeps on getting smarter with better availability of new materials, storage systems, and alternative sources of energy. Though, this paper encompasses all sectors of smart grid, not limited to, smart transmission line, smart distribution generation, smart storage, smart communication, cyber security, and environment friendliness, it has demonstrated the wireless prototype of remote interaction between the consumers and the utility company. In countries like Nepal where power grid infrastructure is limited mostly to cities and energy supply is far below its demand, there is a great potential for energy market growth having minimal barriers to renewables.

Cyber security is important of power grids to ensure secure and reliable power supply. This paper presented a cyber- secure framework for power grids based on federated learning. In this framework, each entity, which may be a distribution/transmission/generation service provider or even a customer, can contribute to the overall system immunity and robustness to cyber-attacks, while not required to share local data, which may have privacy, legal and property concerns. The main idea is to use the federated learning framework to share the knowledge learned from local data instead of sharing power grid data itself. With complete knowledge learned from all data from the power grid, each entity is better positioned to defend the cyber-attacks and improve power grid resiliency. Future work on applying this federated learning based framework in power systems is also discussed.

To comply with electric power grid automation strategies, new cyber-security protocols and protection are required. What we now experience is a new type of protection against new disturbances namely cyber-attacks. In the same vein, the impact of disturbances arising from faults or cyber-attacks should be surveyed by network vulnerability criteria alone. It is clear that the diagnosis of vulnerable points protects the power grid against disturbances that would inhibit outages such as blackouts. So, the first step is determining the network vulnerable points, and then proposing a support method to deal with these outages. This research proposes a comprehensive approach to deal with outages by determining network vulnerable points due to physical faults and cyber-attacks. The first point, the network vulnerable points against network faults are covered by microgrids. As the second one, a new cyber-security protocol named multi-layer security is proposed in order to prevent targeted cyber-attacks. The first layer is a cyber-security-based blockchain method that plays a general role. The second layer is a cyber-security-based reinforcement-learning method, which supports the vulnerable points by monitoring data. On the other hand, the trend of solving problems becomes routine when no ambiguity arises in different sections of the smart grid, while it is far from a big network’s realities. Hence, the impact of uncertainty parameters on the proposed framework needs to be considered. Accordingly, the unscented transform method is modeled in this research. The simulation results illustrate that applying such a comprehensive approach can greatly pull down the probability of blackouts.

For many countries the physical transport infrastructure is critical to the economy, with ports forming a gateway for the majority of trade, and rail and road used to distribute goods. Airlines are crucial to the tourism industry. Whilst the focus of cyber-defense is on financial networks and the power grid, recent incidents illustrate that the transport infrastructure is also susceptible to cyber-attacks. The chapter provides an overview of cyber-security incidents related to the transportation sector, and analyses the reports of the incidents to illustrate the prevalence of threat types and impact. The chapter then discusses some efforts to mitigate the threats in terms of regulations, threat intelligence and information sharing, and awareness training.
