The energy needs of the 21st century are growing rapidly due to the population growth and considerable efforts are being made to make the electricity grid more intelligent in order to make it more responsive to the energy needs of the consumers and to provide improved efficiency and reliability of power systems. Internet of Things (IoT) has emerged as one of the enabling technologies for a smart grid network. As the IoT connected devices continue to grow at a rapid pace, one of the major challenges is security since the devices are online hence making the smart grid vulnerable to significant attacks. Since an IoT based smart grid would consist of potentially millions of nodes, it has the largest attack surface for an IoT focused cyber-attack. A cyber-attack on a smart grid would have devastating effects on reliability of widespread infrastructure given the potential cascade effects of shutting down the electricity grid since most of the devices in our homes, offices, hospitals and trains require electricity to run. Once a single device is compromised, then the whole grid becomes vulnerable to cyberattacks. Such attacks on electricity supply can grind entire cities to a halt thereby causing huge financial and economic losses. This makes security a critical factor to consider before large scale deployment of IoT based smart grid networks.

In this paper we review and explore the major challenges and security issues stunting the growth of IoT-based smart grid networks.

由于人口的增长，21世纪的能源需求正在迅速增长，并且人们正在做出巨大的努力来使电网更加智能化，以使其对消费者的能源需求更加敏感，并提高电网的效率和可靠性。电力系统。物联网（IoT）已成为智能电网的支持技术之一。随着物联网连接设备的持续快速增长，主要挑战之一是安全性，因为设备在线，因此使智能电网容易受到重大攻击。由于基于IoT的智能电网可能包含数百万个节点，因此对于以IoT为重点的网络攻击，它具有最大的攻击面。鉴于关闭家庭电网的潜在连锁反应，智能电网上的网络攻击将对广泛基础设施的可靠性造成毁灭性影响，因为我们家庭，办公室，医院和火车中的大多数设备都需要通电。一旦单个设备遭到破坏，整个网格就容易受到网络攻击。对电力供应的这种攻击可能使整个城市陷入瘫痪，从而造成巨大的经济和经济损失。这使得安全性成为大规模部署基于IoT的智能电网网络之前要考虑的关键因素。然后整个网格就容易受到网络攻击。对电力供应的这种攻击可能使整个城市陷入瘫痪，从而造成巨大的经济和经济损失。这使得安全性成为大规模部署基于IoT的智能电网网络之前要考虑的关键因素。然后整个网格变得容易受到网络攻击。对电力供应的这种攻击可能使整个城市陷入瘫痪，从而造成巨大的经济和经济损失。这使得安全性成为大规模部署基于IoT的智能电网网络之前要考虑的关键因素。

在本文中，我们回顾并探索了阻碍基于物联网的智能电网网络发展的主要挑战和安全问题。
