1.1 Introduction

Automation is evolving in every field around us. As a person living in the fastest growing age of technology development, we have moved from room-sized computers to light and portable laptops and from insecure databases to highly secure web browsers. The same is the case for electrical grids. There are several technological developments in this field of automation, and one of them is automation of grid or “smart electrical grid” (SEG). By connecting individual devices and various appliances to a centralized hub and controlling each and every thing through that network is quite fascinating. An SEG allows you to experience high-tech functionality and convenience that wasn’t possible in the past.
IoT has numerous applications in different fields, such as e-health, smart home, smart cities, smart education system, smart transportation, smart agriculture, and smart factories. Above all, SEG has major attraction in academia and industry due to its direct relation with the real-time events [1,2 and 3]. Figure 1.1 depicts the various applications of the smart grid [4,5].
FIGURE 1.1 Modern smart grid system.
SEGs can be classified into two broad categories based on controlling methodology: (i) native controlled and (ii) remotely controlled [6]. The former system depicts that users can control grid appliances by using controllers via wireless technologies (e.g., Zigbee, GSM, and Bluetooth) or stationary communication methods, whereas in the case of latter, users can control the electrical grid with Internet connections through mobile phones. Numerous flaws occur while setting up the controlling methodology; thus, the SEG should provide an interface for observing and controlling the appliances [6].

1.2 Pros of Smart Electrical Grid (SEG)

Nowadays, for a fast and reliable connection, wireless communication systems such as Wi-Fi are more promising candidates with ample advantages over wired connections:
  1. Cost-Effective: The installation cost decreases due to the non-requirement of cables in contrast to the wired system where the cable, its material, and laying technology along with the need for experienced professionals add up to the cost.
  2. Easy Deployment, Installation, and Coverage: Remote devices or appliances can be easily accessed wirelessly along with easy deployment and installation.
  3. System Extension and Scalability: Transportation of a native structure is predominantly priceless when, due to novel or distorted prerequisites, augmentation of the scheme is essential. More than wired establishments, in which cabling extension is expensive and time-consuming [7], this makes remote systems an original essence.
  4. Amalgamation of Mobile Devices: With the advancement of the communication technology, wireless platform gives the automation an easier and possible solution, where devices or appliances can be remotely controlled or observed without any physical connections.
  5. Aesthetic Benefits: This not only covers a large area, but also beautifully manages the architecture and gives immense benefits to historical buildings and tourist spots.

1.3 Existing System

Currently, modern electrical grids use a lot of techniques. Different modes of wireless communications are used to transfer data and signals between their various components, such as Bluetooth, Zigbee, Wi-Fi, and Global System for Mobile Communications (GSM) [8]. Bluetooth (HC-05) acts as a slave device and is used for communication between Arduino (Mega) IDE and a smartphone. The operating voltage is 3.6–6V. The Bluetooth Board HC-06 has 6 pins such as State, RXD, TXD, GND, VCC, and EN. Internally, the input/output port of an Arduino board (microcontroller) is programmed using C language/Python and the connection is made to home appliances through Bluetooth BT cell [9].
Zigbee is under radio frequency (RF) communication and uses IEEE 802.15.4 standard. The reflection of the Zigbee standard illustrates the packet routing in a network where a large number of nodes exist and the transmission of data occurs in a zigzag pattern as shown in Figure 1.2. Zigbee supports application in all fields. The main component in Zigbee is its coordinator (ZC), which maintains the network and routing table. This standard has three frequency bands, and the prominent band of use is 2.5 GHz with data rates of 250 and 40 kbps. This method has numerous advantages as per the literature, such as low cost, interoperability, low signal-to-noise ratio, low power consumption, implementation by using any microcontroller, easy deployment of innovations, high data security, and requirement of low bandwidth for minor projects [10] (Table 1.1).

As per the literature, voice control method is used for SEG as shown in Figure 1.3 with the help of Arduino and various wireless technologies such as GSM, Bluetooth, Wi-Fi and NFC. In the reported literature [11,12 and 13], the experiment is conducted on five groups with different voice commands to access fan, light, and utility, and the safety check was performed at a baud rate of 115,200 bps to make an SEG [14]. In addition to smart grid automation, the advantage of the feature along with voice is that the motion of the objects or appliances can be recognized [15]. The grid automation is controlled through voice by using Arduino as a controller, Bluetooth HC-05 module as a wireless communicator, and HC-SR04 as an ultrasonic sensor to detect the motion as shown in Figure 1.3.

1.4 Research Gaps

Technology is advancing in every field, and that’s how the concept of grid automation emerged. Technology is all about making each and every task easier. There are different technologies that are used to automate electrical grids which are discussed. The development and implementation has many problems as follows:
  1. Dependency on Range: The SEG connects all the devices of the grid to the mobile app through...
