Wind solar hybrid power plants — practicality of using alternative energy sources

The global trend of growth in electricity tariffs, which is associated with a continuous rise in the price of non-renewable energy resources on the planet, leads to the fact that we are increasingly decisively and decisively solving the questions of using alternative energy in our lives. One of these "free" energy resources for humanity is the inexhaustible energy of the wind and the sun.

However, scientists have come to the conclusion that their complex application in industry or the private sector is much more efficient than using these energy resources individually. Based on these considerations, the idea of ​​creating mobile wind-solar hybrid power plants was born, using, as you probably already understood, the energy of the wind and the sun as energy carriers.

What are wind-solar hybrid power plants?

This type of mobile power plants is a hybrid inverter type storage system, operating in a complex of both renewable natural energy resources, which are wind and solar energy for mankind, and liquid fuel.

For conditions, for example, in Russia and especially in its middle zone, where the number of windy (cloudy) and sunny days per year is approximately the same, the use of such hybrid wind power plants low power — just ideal for use in the private sector.

Such a hybrid electrical installation for the production of electricity is able to ensure the stability of its power supply in the networks of small cottage villages, country houses and small private enterprises. It is also effective in providing power for various types of scientific and field expeditions, geological surveys, yachting, etc.

The principle of operation and purpose of «hybrid» power plants.

The accumulation of energy obtained from the «» primary sources «in these power systems — occurs in storage batteries, with their voltage 12 or 24 volts. In addition, this direct current from the storage batteries of the station, by means of an inverter, is converted into a voltage of 220V of the supply network and a current frequency of 50Hz.

Power plants of this type are intended for consumers of household alternating current networks with a frequency of 50 Hz and a voltage of 220 V, as well as for consumers of direct current with a voltage of 12, 24 and 48 volts. Such power plants can be used both in stationary conditions, when they are connected to existing household power transmission networks, and for conditions of emergency or emergency situations — as an emergency backup source of power.

Advantages and disadvantages of wind-solar hybrid power plants.

The advantages of wind power plants are as follows:

• Mobility and efficiency when deployed in all weather conditions.

• Possibility of stable supply of electricity to consumers in the minimum necessary quantity.

• Ensuring constancy of the output voltage in the autonomous electrical network.

• There are no deviations and surges in the network.

• Ability to upgrade your electrical network to meet current needs.

• Ensuring ecological standards in environmental protection.

• Minimal maintenance with a long service life of the installation, which is approximately 10-15 years.

• A significant increase in the efficiency (efficiency) of the station due to the simultaneous, optimal combination of different sources of its energy supply — wind energy, solar radiation and fuel for an internal combustion engine (internal combustion engine).

Disadvantages of wind-solar hybrid installations.

• The main and main disadvantage of such power plants is their relatively small capacity to provide energy consumers, despite the mobility of the plants themselves.

Conclusion.

When using a hybrid wind farm, you should know that the solar panels and the wind generator to generate electricity are charging devices that work to store energy in the station's batteries. In relation to such circumstances, the electricity obtained through its production by these hybrid power plants and by the way as well as in other ways should also be saved.
