dc.description.abstractenRelevance of research. Demand Side Management (DSM) is one of the fundamental up-to-date solutions to manage electricity consumption in the developing world of insufficient electricity capacity, increasing fuel costs and problems of environmental polution. DSM provides measures to reduce consumption and expenses. In most developed countries, DSM programmes are widely used as a means of harmonizing generation and consumption regimes in the electricity supply system. In order to apply various DSM options and strategies, analytical and optimization tools are used. This also requires detailed information about dynamics of electricity consumption, system functioning and planning, understanding on peak loads and their variations due to environmental factors. Energy demand side management includes activities made by end-users to modify their consumption in a best possible way for both utility and the customers, but this does not necessarily lead to decrease in the total energy consumption. Demand Side Management is made through implementation of activities in order to produce the desired daily, monthly or seasonal load curves. Relationship of work with scientific programs, plans, themes. Today, the Department of Electricity has widely considered and solved the issues of the introduction of dispersed electricity sources into power supply systems and the development of their control systems. This master's thesis corresponds to GDR №2013-n "Development of scientific and methodological bases of aggregation of virtual power plants and active consumers in the conditions of the energy market". The purpose and objectives of the study. The purpose of the dissertation research is to improve and further develop the mechanisms of electricity demand management in local power supply systems based on the use of Frize power modification. To reach the delivered mark in the robot, the following tasks were addressed: - analyze the mechanisms of demand management in modern energy supply systems; - evaluate special features of modern decentralized (dispersed) power generation systems; - take a look at the methods for assessing the total energy loss in local electrical networks; - evaluate the levels of non-optimality of energy consumption taking into account the parameters of local power supply systems, in particular, when active power is consumed at higher harmonics (the presence of voltage and current harmonics of the same name), as well as taking into account the internal resistance of electric power generators and power line resistances; - to develop algorithms for measuring the reactive power of Frize in local power supply systems. The object of research is the processes of the formation of additional and necessary electricity losses and mechanisms for controlling the demand for electricity in local power supply systems. The subject of the research is the methods and means of optimizing the non-uniformity of electricity consumption processes using the mechanisms of electricity demand control with the use of Frize power modification. The scientific novelty of the results of the master's dissertation is the further development of the methodology of optimization of power consumption graphs using power modification Frize Q F in the case of power consumption control and implementation of programs to manage electricity demand taking into account the parameters of local power supply systems. consumption of active power at higher harmonics (presence of voltage and current harmonics of the same name), and also the account of internal its resistance of power generators and resistances of power lines. The practical significance of the obtained results is: (1) in the formation of a number of ratios to assess the levels of suboptimal transmission and consumption of electricity at active power consumption at higher harmonics (presence of the same voltage and current harmonics) and taking into account the internal resistance of power generators and transmission lines; (2) in the development of software-oriented algorithms for measuring the reactive power of Frieze in local power supply systems, allowing to upgrade the DSM program.uk
