  • The present invention relates to a device and method for regulation of electricity consumption diagram in balancing group by heat pump useful for estates, urban zones and residential houses and for using standing charge of electricity.
  • The electricity compared with other products has one particularity, because it is not storable. There have to be equal the consumption amount of electricity and produced amount of electricity that is why the mains run on stable. An apartment sector has second highest final power consumption. Heating, hot water heating and lighting create main part in this sector. Power consumption depends mainly on heat and hot water consumption in households and power consumption of electric appliances and lighting. Approximately 80% of total power consumption is heat consumption which depends mainly on climatic conditions and this variation can be 10% a year. Absolute amount of power consumption depends largely on heat-technical building characteristics, effectuality of rating system and aeration, their regular maintenance and control but also dweller's behaviour.
  • The power supply present electricity sales to consumer from choices supplier. This field of supply is not regulated and it is going on supply and demand principle. The prices of power supply rest on business affairs and determine individually. In many electric systems, some or all consumers pay a fixed price per unit of electricity. The consumer paid ordered amount of electricity regardless real off-take at buying of electricity. So as not to go over or under taking of ordered amount of electricity it is necessary to monitor and keep to electricity consumption diagram. In the case of the consumption diagram breach to result the deviation of subject of settlement ie. the difference between the agreed quantity of electricity of Subject's balancing group and actual quantity of electricity of Subject's balancing group. Deviation biller's activity aimed to evaluate the deviation and consecutive settlement of individual market participants, which have signed the agreement on settlement of deviation with the deviation biller (so called Subjects of Settlement). Deviation biller registers the subjects of settlement and next-to mentioned activity is necessary in the qualities preservation and supply reliability priority to flexible respond on the deviation origination. It means immediately to ensure additional forces (contract amount excess) or to reduce production of some producers (no off-take).The deviation biller buys these supporting services and for that the additional expenses rise and they are project onto costumers according the ratio in which by breach of self consumption diagram to helped to deviation origination. The price of regulated electricity (using standing charge of electricity) by which are the deviations funded is much higher than price of electricity.
  • The active regulation of mains is possible only on the side of electricity power making and the field of regulation of mains is very difficult process because of large-scale regulation system. Electricity consumers largely have the flexibility in the time when they use the electricity and they can cut their costs. Nowadays there are limited attempts to shut-down of operation part in peak hours of power take-off time for example by regulation system ¼ hour maximum HMP 64, which ensures electricity supply measurement, consumption regulation by choices appliances switch-off and also measuring data archiving and PC visualization. Also regulation by city night lighting, but it is useful only at night.
  • In settings when energy savings during certain periods are desired, meters may measure demand, the maximum use of power in some interval. In some areas, the electric rates are higher during certain times of day, to encourage reduction in use. Also, in some areas meters have relays to turn offnonessential equipment.
  • Disadvantage of technical solutions for producing, distribution and supplying of heat and hot water for example for apartment sector and residential premises consist in that their present management systems and systems of supply of heat and hot water do not allow regulation of electricity consumption by switching off and switching on a heat pump as necessary. Also they do not allow any regulation of electricity consumption, amount and energy input of electricity in arranged heat or hot water circuit dropouts according as unplanned changes, accidents et al.
  • The heat pumps are used only for preparing hot water and heating the houses or residential premises till now. Their return on investment is protected only by high efficiency moreover only if the support price of electricity is applied.
