Device for ensuring power equalization in temporary isolated electric networks, in particular by controlling air conditioning systems in power generation with photovoltaic systems

摘要

Device (3) for controlling plants for the production of electricity, preferably photovoltaic systems (4), and connected thereto power-consuming devices, characterized in that • the systems can be operated both in parallel with the general power grid (5) as in island operation, • the island-based power-consuming devices are subdivided into at least two groups, and • in isolated operation, one group (1) of the power-consuming devices is preferably supplied with electrical voltage and power, while the power output is supplied to a second group (2) consuming equipment is limited to a level available as residual available power, which is a function of the difference between the current power generation opportunity and the power consumption of the first group of power consuming appliances.
