Creation of efficient power generating nodes uniting renewable energy power plants

Рассмотрена задача создания энергогенерирующих узлов, объединяющих ветровые и солнечные электростанции. На базе балансовой модели энергоузла исследовано влияние мощности ВЭС и СЭС и определены коэффициенты отношения установленной мощности станции к мощности нагрузки, обеспечивающие требуемую суточную выработку энергии. Для поддержания мгновенного баланса мощности в узле предложено включить в его состав ГАЭС. Показана необходимость повышения эффективности ГАЭС за счет применения асинхронизированных синхронных генераторов и синтезирована система автоматического управления обратимыми гидроагрегатами.The problem of creation of power generating nodes comprising wind and solar power stations is considered. The impact of the wind farm and the PV station capacities on the possibility of providing a generation and consumption balance in the powernode was investigated based on its balance model. There are determined ratios of the plants installed capacities to the load power are, which ensure the required daily energy output. To ensure coverage of the daily load profile it is proposed to include the PSPP in the node. The daily operating modes of power station were analyzed and the ability of the PSPP to maintain an instantaneous power balance was shown. It is exposed the necessity of increasingthe efficiency of the PSPP during work in the typical for the proposed power node sharply varying modes. For this, it is proposed to use asynchronized generators in the composition of reversible hydroelectric power unit of the PSPP. The automatic control system of the PSPP unit is synthesized, which allows ensuring its maximum efficiency when working with variable water pressure at the station. This opens up opportunities for creating efficient energy generating nodes based on renewable energy sources
