Description

Allocation Method of Demand Electricity Fees for Mixed Electricity Meters at Clients

technical field

The invention relates to power system technology, in particular to a technology of a method for apportioning electricity charges for mixed electric meter demand at a user end.

Background technique

The user-side energy management system is responsible for the power supply and distribution of distribution network users. Usually, a user-side energy management system includes several customers with independent financial accounting, which plays a link between the power bureau and customers.

Grid users charge electricity fees to user terminals, and then user terminals charge electricity fees to users under their jurisdiction. Each user has an independent meter. Consumer electricity meters are usually divided into: smart meters that collect real-time segmental energy and maximum demand, and non-smart meters that can only measure periodic energy.

There is a mixture of smart meters and non-smart meters in the energy metering of multi-user power users. Using a reasonable pricing method can reduce the peak power consumption of multiple customers, reduce the peak time at the same time, and actively guide customers to reduce demand, reduce peak load, and save electricity costs. However, there is no effective hybrid meter demand at present. Electricity charge apportionment method.
