Tariff Based Price Calculation of Hospital Loads Using Fuzzy Logic Controller.

with the invention of new technologies, the consumer demand is increasing and will lead to a higher consumption of electricity usage. This will increase the electricity billing price time to time. Mainly this high bills are due to fixed unit charge of electricity. This can be controlled by tariff based unit price of electricity system. Here the proposed system is a hospital network connected to grid. The system contains three hospital loads critical loads, intermediate loads and noncritical loads and a renewable energy resource. The bidirectional flow of energy is taking place here. The critical loads have highest price structure due to high power quality, for that active filter is used. Intermediate loads have intermediate price structure, it contains passive filter for power quality improvement. The non-critical loads has lowest price structure. The total price with tariff and particular price structure of loads are done by smart meter with fuzzy logic controller.
