Problems solved by technology

Moreover, the high penetration rate of EVs and heat pumps will adversely affect the node voltage and line loss of the distribution network, causing the voltage to exceed the limit, especially the voltage of the end node of the network will drop significantly, affecting normal power consumption, and at the same time will increase the line load loss , running uneconomically

Abstract

The invention discloses a meter and a power distribution network node electricity price calculation method for an electromobile and a heat pump. The method comprises the steps that load aggregators designate an initial electricity consumption plan according to an optimization model, a power distribution network operator calculates node electricity price of the power distribution network and sendsthe node electricity price to various load aggregators before shutdown of the electricity market in the day, and the load aggregators make responses to the node electricity price and make an electricity consumption plan anew. Regarding high permeability EV and HP in the power distribution network, the method adopts DLMP to relieve the blocking problem caused by intensive power consumption of EV and HP, relieves operating pressure of the power grid, ensures that the network voltage is within a specified range, and ensures safe and economical operating of the power distribution network.

Description

technical field [0001] The invention relates to a method for calculating electricity price of distribution network nodes considering electric vehicles and heat pumps, and belongs to the field of intelligent distribution networks. Background technique [0002] With the continuous development and application of smart grid technology, and the penetration rate of distributed energy resources (Distributed Energy Resources, DER) such as distributed generation (Distributed Generation, DG), electric vehicles, heat pumps and energy storage devices in the distribution network continues to increase , the operating state of modern power distribution system becomes more complicated, and the distribution network develops from passive to active. In this context, the locational marginal price (Locational Marginal Price, LMP) has been widely studied as an important market price mechanism. The node price plays an important role in optimizing the energy mix in the electricity market environmen...
