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.

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.

The article substantiates the expediency of improving the legal support for the introduction and use of energy-efficient lighting equipment, as well as smart networks (Smart Grid), taking into account the ongoing digitalization of the Russian economy and electric power industry. The goal of scientific research is formulated, which is to develop practical recommendations on optimization of the public relations legal regulation in the digital power engineering sector. The research methodology is represented by the interaction of the legal and sociological aspects of the scientific methods system. The current regulatory and legal basis for the transformation of digital electricity relations has been determined. The need to modernize the system of the new technologies introduction legal regulation for generation, storage, transmission of energy, intelligent networks, including a riskbased management model, is established. A set of standardsetting measures was proposed to transform the legal regulation of public relations in the field of energyefficient lighting equipment with the aim of creating and effectively operating a single digital environment, both at the Federal and regional levels. A priority is set for the development of “smart” power grids and highly efficient power equipment in the constituent entities of the Russian Federation through a set of legal, economic (financial), edu cational measures.

With increasing changes in the contemporary energy system, it becomes essential to test the autonomous control strategies for distributed energy resources in a controlled environment to investigate power grid stability. Power hardware-in-the-loop (PHIL) concept is an efficient approach for such evaluations in which a virtually simulated power grid is interfaced to a real hardware device. This strongly coupled software-hardware system introduces obstacles that need attention for smooth operation of the laboratory setup to validate robust control algorithms for decentralized grids. This paper presents a novel methodology and its implementation to develop a test-bench for a real-time PHIL simulation of a typical power distribution grid to study the dynamic behavior of the real power components in connection with the simulated grid. The application of hybrid simulation in a single software environment is realized to model the power grid which obviates the need to simulate the complete grid with a lower discretized sample-time. As an outcome, an environment is established interconnecting the virtual model to the real-world devices. The inaccuracies linked to the power components are examined at length and consequently a suitable compensation strategy is devised to improve the performance of the hardware under test (HUT). Finally, the compensation strategy is also validated through a simulation scenario.

Abstract We study the quantum simulation of Z2 lattice gauge theory in 2+1 dimensions. The dual variable formulation, the so-called Wegner duality, is utilized for reducing redundant gauge degrees of freedom. The problem of artificial charge unconservation is resolved for any charge distribution. As a demonstration, we simulate the real-time evolution of the system with two static electric charges, i.e., with two temporal Wilson lines. Some results obtained by the simulator (with no hardware noise) and the real device (with sizable hardware noise) of a quantum computer are shown.
