Smart Grid is the seamless integration of advance digital communication network, state of the art control technologies, and power system infrastructure working together as an entity to ensure the reliability, sustainability, and stability of the power infrastructure. Digital communication network with is the key to the reliability of Smart Grid as all control actions are deemed upon the data transmitted by a communication network. With false data, however, the same digital communication network can lead to anomalies like abnormal disruptions, load shedding, malicious attacks and power theft. Robust False data injection attack methods proposed till now demand for the complete knowledge of interconnected power grid network topology. In this paper, three network topology independent techniques for false data injection into the smart grid are proposed based on linear regression, linear regression with time stamp, and by using delta thresholds. To make injected false data more unlikely to be detected, it is constructed to fill up the missing measurements in real-time data. The robustness of proposed attack algorithms are stated by state-of-the-art defence techniques, i.e. Bad Data Detection, AC State estimation, Support Vector Machine, and Temporal Behaviours based False data detection.

With the ever-growing demand of electrical energy and alarming danger of continuously decreasing reserves of conventional fossil fuels, people all over the world are shifting toward the renewable energy resources. Solar being the primary source of energy for the planet is in focus for electrical energy production. This paper enables automatic load transfers between grid and solar generation. It senses the availability of sufficient supply from both sources and automatically switches load between them enabling uninterrupted supply to the load. This paper mainly consists of two major parts one is operational network consisting of solar panel, battery storage, inverter and load, while, the other is control mechanism consisting of Arduino, relays, sensors and switches. The control mechanism senses the output of supply sources and manages the load to operate without any interruption even if the supply from grid is cut off. Thus, it mainly automates the load transfer mechanism between solar and grid minimizing the dependence on conventional energy.
