System for electricity grids for adjusting or matching the electrical demand

摘要

A smart grid management system and method where aggregators do not need to have knowledge about the topology of the electricity grid, the physical location of the end-points they control, or the congestion level of the grid. Instead, the smart grid system and method provides maximum freedom of operation to the aggregators to balance electricity supply and demand in such a way that the danger is reduced or it is even impossible for the aggregators to endanger voltage levels at the distribution system operator (DSO) level or the capacity levels at the transmission system operator (TSO) level. The distribution system operator is allowed to block, interrupt, or change the communication between aggregator and device based on a dual stage-gate control.

1. A method for adjusting or matching electricity demand with electricity production while taking the physical limitations of the electricity grid into account, comprising the steps of:
providing a congestion management system that enables a electricity grid operator to stay in control of the electricity grid; placing the congestion management system into communication between a demand-side-management system used by an aggregator and a device via a standardized device control interface, wherein the aggregator combines the loads and power requirements of more than one electricity account; enabling the electricity grid operator to intercept the communication between the demand-side-management system used by the aggregator and the device at an interception point located on the standardized device control interface by utilizing the congestion management system to allow intervention in demand response control; providing a congestion management agent within the congestion management system; and compiling information about the priority of the device by calculating a congestion management priority value with the congestion management agent.
