A low-carbon benefit assessment method for smart distribution network

Abstract

The invention relates to an intelligent power distribution network low-carbon benefit evaluation method. The evaluation method comprises the following steps: (1) a to-be-evaluated intelligent power distribution network sends collected network and load data information to a load flow calculation module, and the load flow calculation module performs load flow calculation on the overall network, and sends the calculation result to a counterflow tracing module; (2) the counterflow tracing module forms a power digraph of the to-be-evaluated intelligent power distribution network, obtains each value of a countercurrent tracing matrix under the load flow calculation result, and sends the each value to a low-carbon index calculation module; (3) the low-carbon index calculation module performs related carbon-emission theoretical calculation to obtain each low-carbon index calculation result, and sends the calculation result to a low-carbon benefit evaluation module; and (4) the low-carbon benefit evaluation module receives the each low-carbon index calculation result, and performs low-carbon benefit evaluation calculation according to the power grid information of the to-be-evaluated intelligent power distribution network before and after performing a low-carbon plane to obtain calculation results of each low-carbon index of the to-be-evaluated intelligent power distribution network before and after performing the low-carbon plane, and compares the numerical values of the evaluation calculation results to obtain an optimal running scheme for the to-be-evaluated intelligent power distribution network.

Description

technical field [0001] The invention relates to a method for evaluating low-carbon benefits of a power system, in particular to a method for evaluating low-carbon benefits of an intelligent power distribution network. Background technique [0002] The low-carbon benefit assessment of the smart distribution network is based on the power flow tracking technology and the concept of carbon footprint. Through the analysis and calculation of micro-carbon emissions, the measurement of carbon emissions in the power system is converted from the power generation side to the load side. The weak point of the low-carbon development of the power grid provides guarantee for the low-carbon planning and operation of the distribution network. The following is a detailed description of the trend tracking technology and the concept of carbon footprint: [0003] Power flow tracking technology refers to clarifying the distribution of generator or load power in transmission components through pow...

Problems solved by technology

Although the macro-statistical method can define the carbon cost brought about by the power system in each region, it cannot determine the low-carbon responsibility that is accompanied by the support of economic development in the case of power exchange. Being in a weak position is not conducive to the reasonable allocation of low-carbon emission reduction goals in the power system
