Nowadays, smart meters are widely used in power grid, which plays an important role in building the smart power grid and its stability is the key to stable operation of the grid. However, the reliability prediction of the smart meters is difficult to be performed due to its huge number and it cannot be tested one by one. In order to study the prediction method, according to the working principle of smart meters, this paper presents a simulation smart meter model based on Matlab/Simulink software. And related experiments are performed to measure the power consumption under different loads, through comparing the measured power consumption between the simulation model and power analyzer, the correctness of the presented model is verified.

The operation state detection of numerous smart meters is a significant problem caused by manual on-site testing. This paper addresses the problem of improving the malfunction detection efficiency of smart meters using deep learning and proposes a novel evaluation model of operation state for smart meter. This evaluation model adopts recurrent neural networks (RNN) to predict power consumption. According to the prediction residual between predicted power consumption and the observed power consumption, the malfunctioning smart meter is detected. The training efficiency for the prediction model is improved by using transfer learning (TL). This evaluation uses an accumulator algorithm and threshold setting with flexibility for abnormal detection. In the simulation experiment, the detection principle is demonstrated to improve efficient replacement and extend the average using time of smart meters. The effectiveness of the evaluation model was verified on the actual station dataset. It has accurately detected the operation state of smart meters.

With the development of smart power distribution technology in the future, a large range of power supply load (such as distributed wind power generation) will appear on the power receiving end. When distributed wind power is connected to the power grid on a large scale, it will have a certain impact on the safe and stable operation of the power grid. However, if the wind power output characteristics can be analyzed and the wind power output is properly regulated, the one-way flow of power from the distribution network to the user side will be broken, so that the future "network-load" has dual interaction characteristics based on response and substantial power exchange.

Occupancy information is one of the most important privacy issues of a home. Unfortunately, an attacker is able to detect occupancy from smart meter data. The current battery-based load hiding (BLH) methods cannot solve this problem. To thwart occupancy detection attacks, we propose a framework of battery-based schemes to prevent occupancy detection (BPOD). BPOD monitors the power consumption of a home and detects the occupancy in real time. According to the detection result, BPOD modifies those statistical metrics of power consumption, which highly correlate with the occupancy by charging or discharging a battery, creating a delusion that the home is always occupied. We evaluate BPOD in a simulation using several real-world smart meter datasets. Our experiment results show that BPOD effectively prevents the threshold-based and classifier-based occupancy detection attacks. Furthermore, BPOD is also able to prevent nonintrusive appliance load monitoring attacks (NILM) as a side-effect of thwarting detection attacks.

Electronic and smart electricity meters traditionally use as user interface liquid crystal displays due to low cost and proven technology. This paper presents the integration of a flexible electrophoretic display on a smart meter and the possible use cases of such a display. The two main benefit of EPD displays are image retention which can be used as read without power feature and lower power consumption compared to LCD for smart meters. The smart meters available on the market use batteriesor super capacitors for the read without power feature and require each 20ms tenths of mA to displayinformation on the LCD.

The testing approach is facing many difficulties regarding the actual implementations in the modern smart power grids. One of these challenges is the testing of hardware devices such as protective relays, PMUs, and smart meters before its final deployment to the power grid. One way to overcome this is the real-time simulation of power grid. The hardware-under-test (HuT) is plugged to a real-time simulator via signal conditioning circuit (SCC). SCC is an interface circuit involving power amplifier and measurement sub-circuit between the real-time power grid simulator and the HuT. In this chapter, some advanced developed techniques and approaches will be presented.

A smart grid is an advanced utility, stations, meters, and energy systems that comprises a diversity of power processes of smart meters, and various power resources. The cyber-physical systems (CPSs) can play a vital role boosting the realization of the smart power grid. Applied CPS techniques that comprise soft computing methods, communication network, management, and control into a smart physical power grid can greatly boost to realize this industry. The cyber-physical smart power systems (CPSPS) are an effective model system architecture for smart grids. Topics as control policies, resiliency methods for secure utility meters, system stability, and secure end-to-end communications between various sensors/controllers would be quite interested in CPSPS. One of the essential categories in CPSPS applications is the energy management system (EMS). The chapter will spotlight the model and design the relationship between the grid and EMS networks with standardization. The chapter also highlights some necessary standards in the context of CPSPS for the grid infrastructure.

A smart meter is an advanced meter which measures power consumption in much more accurately than a conventional meter and communicates the collected information back to the usage for load limit and tariff purposes. The objectives are privacy that nobody can obtain power usage of other person’s information if the protocol is accurately executed. Real time authentication that transmitted message can be real timely authorized by the receiver which is essential to resist against the denial of service (DoS) attack, Replay attack resistance that receiver can validate whether the received messages are the replay of previously authorized persons. The main objective of this new technology is the bidirectional flow of information. The smart meters send the power consumption reports to the power operator and also control instructions are sent from electricity board in order to be executed by the smart meters. In between, there consists of some gateways which are responsible for data accumulation. The main objective of the system is the communication of smart meter and neighborhood gateway. The presented communication scheme must consider the necessity for consumption reports transmission in short time intervals, and also it must consists of both security and the limited resources of smart meters. This implemented system demonstrates substantial reduction in storage space and data modifications are avoided.

The network is created through a mixture of IT, communication technology and electrical power systems. The smart grid means it is “smarter” in the sense it has its own intelligence hence a smarter power grid. The generated resources are being decentralized by the smart power grids. The major challenges with the smart grid include huge number of smart meters. Due to the large traffic and limited bandwidth, scheduling is very important. Traditional algorithms will maximize the throughput or minimize the average delay may not be valid in smart grid. Power grid plays an important role in datacenters which forms the backbone for the cloud computing infrastructure. The cloud computing and smart grid interacts through the datacenters. The load balancing and robustness can be achieved through this datacenter and cloud system. Many cloud computing features help to achieve this load balancing.
