Transition to digital technologies in management of power industry at all levels – an inevitable consequence of the technical progress which has generated opportunities for diversification, decarbonization and decentralization. Thus it is necessary to recognize that digitalization in power industry is NOT automation, and first of all creation of new business models, services and the markets with a support on possibility of digital economy. In this article questions of transformation of architecture of power industry, and also the main restrictions are considered: absence in regulatory base of new opportunities for consumers; general system inefficiency; impossibility “to legalize” appearance of new subjects (active consumers and prosumers, operators of micropower supply systems and aggregators of the distributed power objects, various service organizations), and also to deregulate the relations between them, to standardize interaction interfaces with EEC, to transform the energy markets.In article it is offered for transition to new digital power to make corresponding changes to the legislation: to enter new type of participants of the market (the active consumer, an active power complex), operated intellectual connection carrying out the standard with the electrical power system, completely responsible for management of the power supply and thus having the minimum regulatory restrictions on organizational model of the work; to improve rules of functioning of trade systems for creation of the markets of the distributed power providing an effective exchange of goods and services between traditional participants of the markets and participants of new type; to enter possibility of application of technologies of the coordinated management of the distributed sources and consumers of energy, systems of storage of energy, means of regulation of loading (“aggregators”) for the purpose of increase of efficiency of their use and participation in the electric power and power markets, including rendering system services and performance of other functions in these markets (the pilot project of such system is realized under the leadership of the author of the present article by subsidiary PAO “Lukoil” “Energy and gas of Romania”); to increase technological and economic flexibility of conditions on reliability and quality of power supply, creation of possibility of a choice by the consumer of conditions of power supply necessary for him and the account them in cost; to enter the accounting of the opportunities given by “new” decisions, at an assessment, formation and implementation of investment programs of the adjustable companies (including introduction of a technique of an assessment of investment projects at possession cost on all life cycle of the decision); to replace cross subsidizing of the population by industrial consumers with mechanisms of address social support and / or with system of restriction of volumes of consumption on reduced rates (“соцнорма”); to refuse further deployment of system of subsidizing of power supply of one regions at the expense of consumers of other regions (as it leads to growth of inefficient power consumption in the subsidized regions, not provided with available generation and infrastructure); to change norms of technical regulation, norms of design on the basis of new technologies; to make changes to programs of development of the infrastructure organizations of power industry taking into account trends of diversification, decentralization, decarbonization and a digitalization; to provide possibility of stimulation, including tariff, implementation of regional programs (pilot and regular), aimed at the complex development of power industry on the basis of new approaches, technologies and the practician, and also the hi-tech companies of small and medium business providing development.

This chapter is about the intelligent techniques for the analysis of power quality problems in electrical power distribution system. The problems related with electrical power industry are becoming more widespread, complex, and diversified. The behaviour of power distribution systems can be monitored effectively using artificial intelligence techniques and methodologies. There is a need of understanding the power system operations from power utility perspectives and application of computational intelligence methods to solve the problems of the power industry. The real power quality (PQ) data is taken from a power utility in Victoria Australia. Principal Component Analysis Technique (PCAT) is used to reduce the large number of PQ data attributes of the power distribution system. After the pre-processing of PQ data using PCAT, intelligent computational techniques will be used for the analysis of power quality data. Neural network techniques will be employed to estimate the values of PQ parameters of the power distribution system. The Feed Forward Back Propagation (FFBP) neural network and Recurrent Neural Networks (RNN) are used for intelligent estimation of PQ data. The results obtained through these intelligent techniques are compared with the real data of power utility in Victoria, Australia for stability, reliability and enhanced power systems performance.

Conventionally in many countries, electrical power industry is organized as vertically integrated system. Under this system, large utilities are authoritative for the generation, transmission and distribution of electrical power. Such utilities are governed by the rules and regulations of the government and are forced to operate within the prescribed guidelines with minimal profit. This confirmation causes an ineffective and sluggish perspective in power industry with a lack of technical innovation, competent management and customer satisfaction. To overcome these deficiencies, power sector around the globe is getting restructured. This paper addresses an inevitable technical disputes occurring in deregulated environment i.e., transmission congestion which has an adverse effect on system security, increase in electricity pricing and line losses. Flexible AC Transmission System (FACTS) is a boon to the power sector which helps in a better and reliable power flow through the transmission lines. The problem is articulated as a multi objective function satisfying all the operational and security limits. Three heuristic algorithms namely Particle Swarm Optimization (PSO), Symbiotic Organism Search (SOS) and hybrid Quantum based PSO-Bio-geography based krill herd optimization (Q-PSOBBKH) algorithms were applied in finding solution to this complex congestion problem. To study the effectiveness of the proposed objective, IEEE 14 bus system was considered as the test system. In order to validate the proposed methodology three congestion cases i.e. bilateral transaction, multilateral transaction and overloading were imposed on the test bus system. Simulation was carried out in MATLAB.

This paper examines the data collected from the power industry over the last six years of actual reported emissions of sulphur hexafluoride (SF6) and the potential impact. The SF6 emissions have been collated from the 14 different regions in England, Scotland, and Wales (Great Britain) from the six distribution network operators. The emissions of SF6 due to the transmission network of Great Britain have also been collated from the three different transmission network operators. By collecting this SF6 emissions data from the power industry, in both the distribution and transmission networks, an overall view of the scale of SF6 emissions in Great Britain can be evaluated. Data from the power industry also shows the inventory of SF6 power equipment in use over the last six years in Great Britain and shows the calculated percentage leakage rate of all of this equipment. In this paper, these figures, as reported by the electrical power industry to the UK government, have been used to estimate the likely inventory of SF6 equipment in England, Scotland, and Wales by 2050 and the future emissions of SF6 that could be leaked into the atmosphere by this equipment.

Electric power industry is the foundation of national economy and plays a key role in the development of human society. Traditional power industry is monopolized by industry and lacked of market efficiency. In recent years, it is seeking breakthroughs in the market-oriented reform. Although China’s electricity market reform has achieved some achievement, it is still lacked of market players, regional transactions, excessive data management, concentration and other defects. This paper puts forward higher requirements for the system design of power market transactions. The electrical power market is facing with the security and performance challenges, it is to improve the electrical power market transaction mode and to enhance transaction security, blockchain is a new decentralized framework and with a distributed computing paradigm, which integrates and innovates a variety of computer technologies, then it constructed a perfect competitive electricity market system. Using of different levels of multi auction trading model to integrate the province’s trading and inter provincial trading parts in one system. In the part of inter-province trading, it adopted the contract trading and bidding coexist pattern, the trade is carried out in each province Surplus-deficit electricity which based on the meet of the province’s demand basis. By using blockchain, it can conducted the intelligent contract and record the whole transaction information discretely, and provided the inquiry transaction channel to the users, so it can achieve the resource scheduling fairness and transaction information in security.
