Power supply planning method suitable for large-scale access of new energy

Abstract

The invention relates to the technical field of power supply planning, and discloses a power supply planning method suitable for large-scale access of new energy. The power supply planning method comprises the following steps of step 1, performing prediction according to load requirements, formulating a conventional power supply planning scheme, and formulating an initial new energy installed scheme on the basis of the conventional power supply planning scheme; step 2, calculating new energy confidence capacity on the basis of the initial new energy installed scheme, and adopting a new energy power supply to replace the conventional power supply according to the confidence capacity to obtain a new energy power supply planning scheme; and step 3, performing new energy consumption capability analysis on the new energy power supply planning scheme; if the new energy consumption capability does not satisfy a new energy rate index, returning to the step 1, and reducing the new energy power supply planning scale; and if the new energy consumption capability satisfies the new energy rate index, completing the power supply planning method suitable for the large-scale access of new energy. By adoption of the power supply planning method, the large-scale development and grid connection of wind energy and solar energy are realized, so that the problems of wind energy and solar energy abandonment are relieved from the power supply planning aspect.

Description

technical field [0001] The invention relates to the technical field of power supply planning, in particular to a power supply planning method adapted to large-scale access of new energy sources. Background technique [0002] In the face of increasingly severe environmental pollution and climate change, new energy represented by wind power and photovoltaics has achieved rapid and substantial development, manifested in continuous increase in installed capacity. While new energy power supply provides clean power, it also brings a series of problems to planning and operation. On the one hand, in order to achieve the goal of reducing carbon emissions and protecting the environment, wind and solar resources are developed on a large scale and connected to the power grid; on the other hand, due to the limited capacity of the system, operators have to abandon wind and light to ensure the safety and reliability of the system However, the high rate of curtailment of wind and light has...

Problems solved by technology

In addition, in terms of power supply planning, the planning of new energy has not received enough attention for a long time, resulting in the disorderly construction of new energy power supplies, which in turn worsened the curtailment of wind and light.
