Анализ экономической эффективности электроснабжения на базе ВИЭ сельского домовладения в средней полосе России

Analysis of the obtained data of the power supply monitoring system of rural housing in the middle land of Russia

Анализ экономической эффективности электроснабжения на базе ВИЭ сельского домовладения в средней полосе России

Abstract

The article considers the power consumption of rural households in the Belgorod region. An assessment was made of the possibility of extending the results of the analysis to other areas of the “middle lane” of Russia. The indicators that allow a positive answer to the questions posed are considered. These are: long-term average wind speed; average long-term specific arrival of solar radiation on a horizontal area of 1 m2; per capita electricity consumption per villager; electricity consumption per 1 m2 of living space of a rural resident. In general, the data indicate a quite satisfactory representation of the results obtained for assessing the possibilities of power supply for households using renewable energy sources in the regions of the "middle lane" of Russia. The ratio of the maximum power consumption to the average power consumption for various averaging periods is determined: 10 seconds, 1 minute, 5 minutes, by months of the year and year. The value of the ratio of these powers indicates the need to consider their overload capacity when choosing inverters, and batteries have limitations when charging and discharging. An assessment of the payback period of four options for power supply systems was carried out: two options based on wind turbines with connection to the grid and stand-alone, and two similar options based on photovoltaic modules. Prices for equipment are taken at the level of the beginning of 2018, that is, before the onset of the crisis due to the coronavirus pandemic, since calculations at the current constantly rising prices are completely meaningless.

Дан анализ электропотребления сельского домовладения в Белгородской области. Определена возможность распространения результатов анализа на другие области средней полосы России. Рассмотрены показатели, позволяющие положительно ответить на поставленные вопросы. Таковыми являются: среднемноголетняя скорость ветра; среднемноголетний удельный приход солнечной радиации на горизонтальную площадку; душевое потребление электроэнергии на одного сельского жителя; потребление электроэнергии на 1_м2 жилой площади сельского дома. В целом данные указывают на вполне удовлетворительное представительство полученных результатов для оценки возможностей электроснабжения домовладения с использованием ВИЭ в областях средней полосы России. Определено отношение максимальной потребляемой мощности к средней годовой потребляемой мощности для различных периодов осреднения: 10_с, 1_мин, 5_мин. Это отношение необходимо учитывать при выборе инверторов, имея в виду их перегрузочную способность, а у аккумуляторных батарей учитывать ограничения при заряде и разряде. Определён простой срок окупаемости четырёх вариантов систем электроснабжения: два варианта на базе ветроэнергетической установки (ВЭУ) с присоединением к сети и в автономном режиме, и два аналогичных варианта на базе фотоэлектрических модулей.
