In the process of power system development planning necessary to have a forecast of electricity demand in the future. The results obtained estimates can be considered for policymakers to formulate measures to be taken for the future. It aims to achieve optimization in the process of supplying electrical energy. To optimize the energy supply of electricity in the province of West Sumatra required an estimation of electrical energy. In this study, estimation methods used are fuzzy logic. Estimates carried out long term, ie until 2018. Estimated long-term electric energy demand is generally based on past statistics and analysis based on energy consumption characteristics ago. Such characteristics are usually influenced by several factors, such as population, number of electricity customers, electrification ratio, and so forth. The fuzzy logic method uses historical data / actual accumulated in several time periods, namely from 2000 to 2008. Results estimated by using fuzzy logic shows that the electrical energy needs in West Sumatra province in 2018 amounted to 3610 GWh. This value is not much different from the estimates made by PLN, which amounted to 3998.5 GWh. Error between the estimated value of fuzzy logic in 2018 and PLN was 5:48%.

The balancing of the power of the Polish Power System (KSE) is a key element in ensuring the safety of electric energy supplies to end users. This article presents an analysis of the power demand in power systems (PS), with emphasis on the typical power variability both in subsequent hours of the day and on particular days and in particular months each year. The methodology for calculating the costs of electric energy undelivered to the end users and the amount of these costs for KSE is presented. Different possibilities have been analyzed for balancing power systems’ peak load and assumptions have been formulated for calculating the amount of the related costs. On this basis, a comparative analysis has been made of the possibility to balance peak load using operators’ system services, trans-border connections, and various energy storage solutions. On the basis of the obtained results, optimal tools have been proposed for market-based influence from transmission and distribution system operators on energy market participants’ behaviors in order to ensure the power systems’ operating safety and continuous energy deliveries to end users.

Introduction. The world market of electrical equipment is developing very fast. There are many companies in the market that sell electrical equipment, among them there are companies that occupy leading positions. Today, the world market of energy engineering is estimated at 87 billion dollars per year, based on the structural dynamics of growth, the annual volume can reach 110-115 billion dollars per year until 2025. The global market for energy equipment service in 2020 is 31.7 billion dollars, including: LTSA (long-term service) 47 %, modernization – 20 %, field service – 24 %, engineering – 9 %. The purpose of the paper is to analyze the world market of electrical equipment, determine sales, business growth. The list of leaders in electrical equipment on the world market is considered. Results. The main trends in the world today are the following areas: development of DC transmission system, cable lines for underwater laying and cable for connections of renewable energy sources to reduce energy transmission costs through the capabilities of existing transmission lines, through network voltages and innovative design solutions and installation methods. The amendment for these trends shows us the world leaders in the electrical market, such as Legrand, Schneider Electric, ABB, Siemens, DEKraft, SASSIN, EKF, etc., R&D costs are 3.5–5 % of profits (over 60 years). Thus, we can conclude that the global market for cable networks is developing rapidly. This market is expected to grow in the development of smart grid technologies, renewable energy generation and initiatives to modernize the transmission and distribution system. Conclusion. That the global cable ladder market is developing rapidly. This market is expected to grow in the development of smart grid technologies, renewable energy cultivation and government initiatives to modernize transmission and distribution systems.

Smart Grid Technology

The term "smart grid" refers to the transformation of the traditional electric power grid into a modern grid. Modernization of the present electric power system is an important step to implement the Smart Grid technology. The structure of the existing power sector in Bangladesh is almost a hundred years old. Due to which the power sector of Bangladesh facing huge power wastage. A Smart Grid also ensures the efficient transmission and distribution of electric power. This paper gives a brief description of Smart Grid, the latest trends, challenges, prospects, cost analysis of smart grid equipment, and its facility. The spotlight of this paper is to implement the Smart Grid's perspective to Bangladesh. That’s included to have new distributed generation technology, smart meter, a pilot project, etc. Also, the main objective of this paper is the comprehensive development of transmission and distribution loss reduction, which will be saving a big amount of capital every year. And that will play a huge role in the economy of Bangladesh to move forward in global progress.

Energy Supply Security

In this paper, an analysis of issues related to development of national electric power network infrastructure in aspect of electric energy security is performed. Profile of network infrastructure in area of transmission and distribution is performed. Threats for electric energy supply security connected with transmission and distribution infrastructure are discussed. Both transmission and distribution electric power network are adapted for presently occurred typical conditions of electric energy demand and realization of internal tasks in normal conditions, but can create potential threat for electric energy supply security. In the context of forecasted increase of electric energy demand, inadequate power in National Electric Power System (NEPS) in domestic sources and available through intersystem connections, uneven location of sources and consumers at shortage of proper network transmission capacities, necessity of improvement of quality and electric energy supply reliability to final consumers and intensive development of renewable energy sources, present network infrastructure in area of transmission and distribution will be insufficient. Development of 400 and 220 kV transmission network, 110 kV distribution network especially in area of cities, MV distribution network especially in rural areas and realization of investments for improvement of export-import possibilities of NEPS will be necessary. Challenges for transmission and distribution system operators in area of network development are performed. They concern mainly investment sphere and area connected with preparation and construction of network investments.

Purpose – There is a great interest from the European Union in measuring the efficiency of energy use in households, and this is an area where EDP has done research in both data collection and methodology. This paper reports on a survey of electric energy use in Portuguese households, and reviews and extends the analysis of how efficiently households use electrical energy. The purpose of this paper is to evaluate household electrical energy efficiency in different regions using econometric analysis of the survey data. In addition, the same methodology was applied to a time-series data set, to evaluate recent developments in energy efficiency. Design/methodology/approach – The paper describes the application to Portuguese households of a new approach to evaluate energy efficiency, developed by Filippini and Hunt (2011, 2012) in which an econometric energy demand model was estimated to control for exogenous variables determining energy demand. The variation in energy efficiency over time and space could then be estimated by applying econometric efficiency analysis to determine the variation in energy efficiency. Findings – The results obtained allowed the identification of priority regions and consumer bands to reduce inefficiency in electricity consumption. The time-series data set shows that the expected electricity savings from the efficiency measures recently introduced by official authorities were fully realized. Research limitations/implications – This approach gives some guidance on how to introduce electricity saving measures in a more cost effective way. Originality/value – This paper outlines a new procedure for developing useful tools for modelling energy efficiency.
