A key feature of the smart grid is automation technology that lets the utility adjust and control each individual device or millions of devices from a central location. A Smart Grid must functions as followings 1. Be able to heal itself Smart Grid is designed with a control system that self-analyzes its performance using intelligent autonomous reinforcement learning controllers that are able to learn new strategies and successfully implementing such strategies to govern the behavior of the grid in the face of an ever changing environment such as equipment failures. 2. Motivate consumers to actively participate in operations of the grid If consumers have freedom to control own usage of energy, they will be motivated to participate and be part of the system. They can monitor their usage and manipulate by the assistance of “smart appliances” and “intelligent equipment” in homes or businesses. Advanced communications capabilities equip customers with tools to exploit real-time electricity pricing, incentive-based load reduction signals, or emergency load reduction signals. 3. Resist attack Most important issues of resist attack is the smart monitoring of power grids, which is the basis of control and management of smart grids to avoid or mitigate the system-wide disruptions like blackouts. 4. Accommodate all energy generation and storage options Smart Grid integrates two power generation source; traditional power generation likes fossil fuel powered power plant with renewable power generations either generates from residential, commercial, and industrial customers that will improves reliability and power quality, reduces electricity costs, and offers more customer choice. 5. High quality power Outages and power quality issues is common for any country especially for major industrial-based countries. Smart Grid provides more stable power provided that will reduce downtime and prevent such high losses because of

As digital technology becomes more deeply embedded in power systems, protecting the communication networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3) represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities. Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network (CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to train and test our model. The results of our experiments show that our CNN-LSTM method is much better at finding smart grid intrusions than other deep learning algorithms used for classification. In addition, our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection accuracy rate of 99.50%.

SUMMARY - Current power grids increasingly emerging into smart networked grids and are more accessible from the public internet which poses new cyber threats in the grid. More computer based systems are introduced into power networks in order to monitor and control the network. Future model smart grid and micro grid systems will be based on data flows for communication of system status, usage and control throughout the network infrastructure in addition to the power flow. This creates new security threats on the power grid. Instead of relying mainly on power plants for power generation, there will be a combination of multiple generation sources and at the same time wider use of electrical computer based equipment by consumers. Both increase the amount of data flows in the network as well as introduce additional vulnerable spots. Vulnerability of the power grid to cyber-attacks increases even more because of the wide use of SCADA networks. SCADA networks are more accessible to the internet and lack authentication and authorization mechanisms therefore expose the grid to threats such as DDOS, Data interception, Data alteration and additional hacking threats. The transition from present to future model has already begun and rapidly growing while it already poses new security challenges which must be attended immediately. It is essential to introduce immediately a single comprehensive security solution which will provide fast detection and prevention tools to cope with a variety of threats with different nature and from multiple sources. The solution should not be tightly coupled with each device in the network so it won’t require upgrade of the devices inside the grid. The Cyber defense solution should be versatile using variety of cyber technologies such as Firewalls, anomaly detection, Big Data analytics, machine learning and more in a network wise combination.
