Development of society and economy affects the increasing consumption of electricity, which leads to greater production and higher system load. In addition, the number of renewable sources of electricity has also increased remarkably. Primarily this implies to solar and wind power plants, which cannot traditionally be adapted to the consumption. This leads to a key problem of balance between consumption and production of electricity.
Traditionally, electricity production was adapted to the consumption. Today, due increased sources of renewable resources (solar, wind power), adjustment of production to the consumers has become more and more difficult. The main problem still remains that we are unable to save large quantities of produced electricity. At this moment, the only possible way is to include consumption in system and maintain the balance between the two. Nowadays, economic possibilities and flexibility offer much better conditions than few years ago. Also the costs of telecommunications, electronic devices, data processing and data storage have dropped significantly. This has increased the interest for demand response systems. With these systems, electrical consumers are more actively included in the electricity network and are no longer only traditional electricity consumers. We also increase usability, utilization and integration of renewable resources (solar, wind power) into the electrical system.
This bachelor thesis describes management of household appliances (below 43 kW of power) with remotely controlled devices. Presented intention is reducing peak load of electrical system network, without installation of any new infrastructure. Network's load would be reduced and better utilized. Presented devices will be used on the pilot project and are still in the development phase. Solutions are presented with different modules although all have the same goals.
