Problems solved by technology
DISCO cannot change the interests of DG units, nor can it encourage them to form more partnerships in loss reduction and emission reduction
LMP can only be calculated under current operating conditions, and these methods cannot estimate LMP in the next step of network operation
And ignore the private ownership characteristics of the DG unit, and think that the DG bus has a unified price
Considering that the unified price of the DG bus restricts the production of DG, DISCO cannot control the private DG to reduce line loss and emissions
[0004] Aiming at the problem in the above-mentioned related technologies that the emissions generated by the distributed power unit itself are not considered when adjusting the node marginal electricity price, no effective solution has been proposed so far

The invention discloses a node marginal electricity price adjusting method and device. The method comprises: determining reference parameters of a distributed power supply DG unit in a power distribution network, wherein the reference parameters comprise reference network power loss and reference pollutant discharge amount; determining actual parameters of a DG unit in the power distribution network, the actual parameters including actual network power loss corresponding to the DG unit and actual pollutant discharge corresponding to the DG unit; determining a predetermined network power loss amount and a predetermined pollutant discharge amount allocated to the DG unit according to the reference parameter and the actual parameter; and adjusting the node marginal electricity price of the DGunit according to the actual parameters, the predetermined network power loss amount and the predetermined pollutant discharge amount. According to the method and the device, the technical problem that the emission load generated by the distributed power supply unit is not considered when the marginal electricity price of the node is adjusted in the related technology is solved.
Description
technical field [0001] The invention relates to the field of node marginal electricity price adjustment, in particular to a node marginal electricity price adjustment method and device. Background technique [0002] In recent years, nodal marginal prices have been considered in distribution systems. For example, in "Nodal pricing for distribution networks: Efficient pricing for efficiency enhancing DG", the node marginal pricing (LMP for short) in the distributed system was proposed for the first time. Efficient method, which is further developed in "Towards a cost causation-based tariff for distribution networks with DG", where the concept of marginal line loss is used to determine the share of each bus in the total line loss. "Sensitivity-based pricing and optimalstorage utilization in distribution systems" develops distributed node marginal power price LMP signals based on power flow sensitivity, and also develops sensitivity analysis based on Jacobian functions for dist...
