- 4. ADVANTAGE OF SMART GRID
- 5. NEED FOR MICRO GRID • With smart grid, we're talking about dams, massive solar farms etc. The scale is extremely large. • Microgrid is a small-scale power supply network that is designed to provide power for a small community. • It enables local power generation for local loads • It comprises of various small power generating sources that makes it highly flexible and efficient • It is connected to both the local generating units and the utility grid thus preventing power outages. • Excess power can be sold to the utility grid. • Size of the Microgrid may range from housing estate to municipal regions
- 6. ARCHITECTURE OF MICRO GRID
- 7. CYBERSECURITY IN MICRO GRID • Power grid is a huge, complex, critical and expensive infrastructure. • ICT makes the grid Smart Real time monitoring (PMUs, Smart meters) Advanced information analysis (Big data) Automated control (Self-healing, Smart actuators) • ICT also make the grid Vulnerable!!! • The security goal in Smart grid is the Availability, Integrity and Confidentiality • Some solutions were proposed to solve security issues in the smart grid, vulnerabilities still exist.
- 8. SECURITY ISSUES & SOLUTIONS • Man-in-the-middle attack • Reliable data transmission protocols with ACK and NACK feedback mechanism. Intelligent module: Monitor the distribution pole • Denial of Service (DoS) • Security firewalls used to differentiate between legitimate and malicious traffic • Increase in bandwidth ZigBee: Communication module • Confidentiality and Integrity • Cryptography-Hashing the data Smart controlling station: Billing and data storage
- 9. MOST COMMON ATTACKS AND SOLUTIONS To ensure valid data transmission : OTP, MAC, Time stamp technique Effect communication channel: DSSS spread spectrum, In built 128 bit AES encryption standard Key management : Public key infrastructure (PKI), ensures security by verifying the true identity of the party. The advantage of symmetric key management over the PKI is speed and efficiency Replay attack Jamming Authentication
- 10. CONCLUSION • Smart grid has numerous benefits like lower cost, high reliability and efficiency. • ICT are at the core of successful smart grid implementation, which can improve reliability, security and efficiency. • A Power grid can be make smart grid by using the combination of information technology, communication technology and electrical system. • Cyber security in the smart grid is still under research and needs more investigation to overcome the vulnerabilities and threats. • Cyber security in the smart grid is a critical issue that received attention of researchers and industry professionals.

Editor's Notes
- #4: ICTs stand for information and communication technologies and are defined, for the purposes of this primer, as a “diverse set of technological tools and resources used to communicate, and to create, disseminate, store, and manage information.”
- #8: Security Requirements and Objectives Availability : Accessing information in a timely in the smart grid. Integrity : Preventing an unauthorized modification of information or system by illegitimate users. Confidentiality : Preventing unauthorized users from accessing information in order to protect personal privacy and safety.
- #9: Intelligent module consist of the VI sensor to monitor phase line. Processor checks value from sensor (if value>preset threshold: Circuit breaker opens the line.) [MitM is between sensor and micro controller, sensor data can vary, if value change and current flows beyond threshold limit=appliance explode and electric shock] Circuit breaker: In appropriate access by an unauthorized personnel ZigBee: Dos {Due to trojan or disproportionate uploading of large files} SCS: The data stored in the SCS should be secured in terms of programming, hardware components and communication protocols. Data confidentiality prevents unauthorized disclosure. If confidentiality is maintained, it will ensure the trust, dignity and respect of the users.
- #10: Key management Key management plays a significant role in authentication and encryption to achieve a secure system. It is categorized into : • Public key infrastructure (PKI) : ensures security by verifying the true identity of the party. • Symmetric key management : It is used in symmetric cryptography. The advantage of symmetric key management over the PKI is speed and efficiency
