New energy receiving-end grid absorptive capacity assessment method supporting multi partition

Abstract

The present invention discloses a new energy receiving-end grid absorptive capacity assessment method supporting multi partition. The method takes maximization of absorptive capacity of new energy received into a power grid as a target, considers the partition load balance constraint, call wire plan constraint, set operation constraint and power grid safety operation constraint of the new energy receiving-end grid, employs a linear planning method to perform optimization calculation of a set output plan and a call wire plan and calculates the maximum absorptive capacity of new energy of the power grid in an assessment period so as to provide transaction auxiliary decision for the trans-provincial and trans-regional new energy transaction.

Description

technical field

[0001] The invention relates to a method for evaluating the consumption capacity of a new energy receiving end power grid supporting multiple partitions, and belongs to the technical field of power system scheduling automation. Background technique

[0002] New energy represented by wind power has gradually become an important direction of energy development due to its non-polluting and renewable characteristics and no greenhouse gas emissions. In particular, wind power, as one of the most mature new energy utilization methods, has achieved rapid growth for many years with the strong support of the state. In 2015, the new installed capacity of wind power in the country was 30,753MW, and the cumulative installed capacity reached 145,362MW; the newly installed installed capacity of photovoltaic power generation in the country was 15,130MW, and the cumulative installed capacity was 43,180MW. Among them, the Northwest region is still the region with the largest ...
