Problems solved by technology

The current DC cross-regional and inter-provincial transmission methods mostly arrange the power transmission plan according to the operation requirements of the power station itself or the power surplus of the sending-end power grid, and rarely take into account the power demand of the receiving-end power grid, resulting in the receiving-end power grid having to passively consume a

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0023] In the evaluation and calculation process of the new energy consumption capacity of the receiving-end power grid, it is necessary to combine the load forecast of each partition system, the connection line plan and the availability status of each unit on the next day, as well as the distribution coefficient of each channel for new energy access. The proportion of new energy consumption in each partition, considering factors such as partition load balance constraints, unit operation constraints, and power grid security constraints, calculates the new energy consumption capacity with the goal of maximizing the new energy consumption capacity of the receiving end grid, and calculates the new e...

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 ...
