| description |
Purpose. Improving the principles of management of photovoltaic system with storage battery and with autonomous functioning during daylight hours for a local object, connected to the grid with multi-zone payment when excluding the generation of energy into the grid. Methodology. Modeling and analysis of energy processes in the photovoltaic system was performed using the Matlab software package. The simulation model of energy processes is based on calculated expressions taking into account the characteristics of the battery. Operability of the proposed solutions are confirmed on an experimental setup based on a standard hybrid inverter. Results. It’s shown, that due to the battery energy during the most loaded peak hours and part of the daytime the system operates autonomously and does not depend on possible violations of the quality of electricity in the grid. Scenarios of the recommended load schedule are proposed in accordance with the ratio of the predicted value of the daily energy generation of the photovoltaic battery to its possible maximum value. A simulation model of energy processes in the system with the correction of the recommended load value was developed. Originality. A method of the recommended load calculation with current correction for the actual generation and degree of battery charge is proposed, which allows taking into account differences the actual generation of the photovoltaic battery from its predicted value and the actual load from the recommended one. Practical value. The obtained solutions are the basis for the design of new and modernization of existing photovoltaic systems of local objects using software and hardware complexes for power consumption management. |

Усовершенствованы принципы управления и перераспределения энергии, накапливаемой в аккумуляторной батарее, в фотоэлектрической системе локального объекта, подключенного к сети с многозонной тарификацией при исключении генерации энергии в сеть. За счет энергии батареи в наиболее нагруженные пиковые часы и частично в дневное время система работает автономно и не зависит от возможных нарушений качества электроэнергии в сети. Предложено сценарии рекомендованного графика нагрузки в соответствии с отношением прогнозируемого значения дневной генерации энергии фотоэлектрической батареи к ее возможному максимальному значению. Предложена методика расчета рекомендованной нагрузки с текущей корректировкой по фактической генерации и степени заряда батареи, что позволяет учесть отличия фактической генерации фотоэлектрической батареи от прогнозного значения и фактической нагрузки от рекомендованной. Разработана имитационная модель энергетических процессов в системе с корректировкой значения рекомендованной нагрузки. Работоспособность предложенных решений подтверждена моделированием в Маtlab и на экспериментальной установке на базе стандартного гибридного инвертора. Полученные решения являются основой для проектирования новых и модернизации существующих фотоэлектрических систем локальных объектов с использованием программно-технических комплексов управления электропотреблением.
