CYBER SECURITY AND CHALLENGES OF THE SMART GRID.pdf 2.pdf
— Cyber security in smart grid systems is becoming a major concern throughout the grid communication networks and software platforms that operate and manage the entire grid. The smart grid networks characteristics such as heterogeneity, delay constraints, bandwidth, scalability, and others make it challenging to deploy uniform security approaches all over the networks segments. Therefore, more research is required to develop standards and techniques that meet the smart grid network requirements at a low cost. In this paper, we discuss some of the existing cyber security issues in smart grid networks, highlight some of the latest solutions, and propose a new security conceptual model based on the Internet of Things paradigm.
Evolving Cyber Security Challenges to the Smart Grid Landscape
Integrating smart solutions into the existing power infrastructure promises to offer attractive capabilities of dynamic monitoring, measuring and even controlling power flows in real time that can help identify losses and trigger appropriate technical and managerial actions to minimize the damage. With the vision of building a Smart India, Government of India's National Smart Grid Mission (NSGM) is solely aimed at providing functional resources and financial assistance in planning and implementation of smart grids across the nation. NSGM proposes comprehensive solutions for the development, establishment, operations and management of smart grids, stipulate training & capacity building, strengthen consumer engagement and dispense funding to state-owned DISCOMs. Smart grid solutions vastly employ information technology in the underlying roots in varying forms of networking and application aspects to enable monitoring and control of the flow of electricity to end users. The extensive incorporation of information technology provides numerous benefits to the grid operations and management, such as increased visibility, predictability, in addition to the regulation of generation and demand to improve efficiency. However, this enhanced use of information technology to the grid has in parallel introduced the dimension of cybercrime to the smart grid as the grid is now constantly connected to the Internet and can be exploited by hackers by leveraging the wide array of cyber security vulnerabilities. Security of the smart grid is essential to ensure uninterrupted power supply and minimize resulting losses. Compromise of the grid may result in a huge information or business losses by the means of cyber espionage or grid collapse. An uninterrupted power supply lies at the heart of all sectors and failures to the same will result in cascading damages, compelling the establishment of robust smart grids. The paper offers insight into key cyber security threats and vulnerabilities concerning the smart grid technology and proposes protection strategies, methodologies, and technologies to safeguard the smart grid from resulting security damages.

A Survey on Cyber Security for Smart Grid Networks
—Smart grid is a electrical grid in which power generation units, transmission units, distribution units and electricity consumers are connected using advanced communication and information technologies. It is a new form of next generation power grid. Most of the countries across the globe are transforming their existing electrical grids to smart grid and hence smart grid technology is progressing worldwide. Smart grid provides a bi-directional flow of electricity and information from generation to transmission to distribution and hence more exposed to attacks. Many advanced communication technologies have been identified for smart grid usages. A secure communication infrastructure is a critical component of smart grid systems. Success of smart grids highly depends on secure communication network. Thus cyber security of smart grid networks is very important. In this paper, we summarize the cyber security threats, possible vulnerabilities and existing standards and solutions available for cyber security in smart grids networks based on the available reference material.
Cyber Security of Smart Grid Infrastructure
CRC Press, USA, 2014
Smart grid security is crucial to maintain stable and reliable power system operation during the contingency situation due to the failure of any critical power system component. Ensuring a 'secured smart grid' involves with a less possibility of power grid collapse or equipment malfunction. Due to lack of the proper 'security measures', a major blackout may occur which can even lead to a cascading failure. Therefore, to protect this critical power system infrastructure and to ensure a reliable and an uninterrupted power supply to the end users, smart grid security issues must be addressed with high priority.
