Medium-and-long-term electric quantity safety checking method and system

Abstract

The invention provides a medium-and-long-term electric quantity safety checking method and system. The method comprises the following steps of step 1, constructing a coupling relationship among main bodies according to acquired basic data, 2, respectively calculating the electric quantity margin of each main body based on the coupling relationship between the main bodies, and taking the electric quantity margin of each main body as the corresponding electric quantity bucket of each main body, 3, distributing a to-be-checked electric quantity plan to the electric quantity bucket corresponding to each main body based on the coupling relationship between the main bodies, 4, respectively comparing the electric quantity buckets with the electric quantity plans of the main bodies, and judging whether the electric quantity plan of any main body exceeds the electric quantity bucket or not, otherwise, ending, and step 5, adjusting the electric quantity plan and going to the step 3. According tothe method and the system, a complex medium-and-long-term electric quantity checking problem is simplified into an electric quantity margin calculation and decomposition process of an electric quantity related main body, i.e., an intuitive process of calculating'barrels' and loading'barrels', so that the understanding and application of operating personnel are facilitated, and the quantitative explanation of electric quantity adjustment of the society is further facilitated.

Description

technical field [0001] The invention belongs to the technical field of electric power system dispatching plan, and in particular relates to a method and system for mid- and long-term power safety checking. Background technique [0002] In the power system dispatching plan, the short-term power generation planning method with security constraint dispatching as the core technology has been widely used in various power dispatching control centers. The short-term power generation plan and safety check do not involve complex power and quantity decomposition, the physical boundaries are clear, and the prediction data accuracy is high. However, if the short-term security check method is used for mid- and long-term security checks, it will cause a large deviation and lose the significance of the check. [0003] With the rapid advancement of electricity market-oriented reforms, the scale of market trading power continues to expand, and the feasible space for grid power generation pl...
