Backup power systems

A high degree of reliability of power supply, which is especially important for rural consumers, can be achieved in several ways:
Improving the reliability of all elements that make up electrical systems, their telemechanization and automation.
Conducting redundancy of power supply lines, for example, powering a transformer substation from several lines. However, in case of strong wind, thunderstorm, ice or freezing of wires, there is a high probability that the main and backup overhead lines can be simultaneously damaged. However, it is not always possible to provide the main and backup power supply, especially in cases when it comes to objects located far from settlements.
The use of reserve solar power plants in combination with energy storage and storage systems allows you to completely avoid interruptions in the supply of electricity, which are caused by planned or emergency outages of the general electrical network. The need to install backup solar power plants is justified in cases where the specific potential damage caused by the disconnection of the general power grid is greater than or equal to the cost of electricity that will be generated by the backup solar power plant.
Standby solar power plants begin to function when there is an interruption in the supply of electricity from the centralized power supply system. Observations show that even in the most unfavorable conditions, the duration of power outages even in the most remote rural areas is no more than 150-200 hours per year. In reality, taking into account the peculiarities of the technological processes of agricultural production, the breaks turn out to be much less, therefore, the capacity of the reserve SPP in combination with the battery pack will be enough to completely replace the arisen power shortage. In addition, the design of a backup solar power plant may provide for the possibility of using it to cover peak electricity needs.
