Дослідження генерування вітроелектроустановок з системами накопичення енергії

Abstract

In this work, the problem of integration of such elements of the electric power network as: industrial energy storage and directly wind generators is investigated. The sharp increase in the share of this type of electricity creates a number of issues that need to be resolved, first of all, the stochastic nature of the work. Solving this problem is relevant not only from the point of view of eliminating the phenomenon of uneven energy generation using a wind turbine, since wind is a variable source of energy, but also increasing the indicators of the interaction of the wind flow with the generator blades, i.e. increasing the permeability of the wind. This problem was noticed during the study of the operation of modern wind systems, especially the period of operation during direct start-up and in the presence of low wind speed, and therefore the efficiency is minimal. In this case, the use of energy storage systems is the best option for integration, as it allows not only to store energy, but also to increase the level of reliability of electricity supply. The work includes an overview of several variations of the location of wind power plants and energy storage systems: local, distributed, centralized. The use of one or another option depends on the size and load of the direct network. In addition, two models of energy storage were investigated in the work: storage in the rear part of the installation and storage in the front part of the installation. The study showed that using the option when the storage systems are located in the front part of the installation increases the weight of the nacelle, which is a negative factor, but installing it in the rear part or next to it increases the level of losses, which is an equally significant factor. In general, the installation of storage systems will complicate the immediate work, and also increase the cost, but in view of the future perspective, the solution to these issues is fully justified. Having solved the technological questions that gradually arise, the process of generating energy based on wind turbines and its synchronized storage will satisfy other important questions.

В роботі досліджено проблематику інтегрування таких елементів електроенергетичної системи як: промислові накопичувачі енергії та безпосередньо вітроелектроустановки. Різке зростання частки такого виду електроенергії формує ряд питань, що потребують вирішення, в першу чергу – стохастичний характер їх роботи. Вирішення цієї проблеми є актуальним не лише з точки зору усунення явища нерівномірності генерування енергії за допомогою вітроелектроустановки, оскільки вітер є мінливим джерелом енергії, а й підвищення показників взаємодії потоку вітру з лопатями генератора, тобто збільшення проникності вітру.
