Problems solved by technology

The actual operation of the power system is affected by various factors, such as the maintenance and failure of power transmission and distribution equipment, the modification of the shutdown plan, the short-term load forecast, the new energy output forecast, and the inter-provincial power transmission and reception plan. Large difference, based on this, the generator set cannot fully execute the power generation output according to the planned curve before the day

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] like figure 1 , the method of the embodiment of the present invention is composed of two parts: determining the deviation distribution strategy between the network provincial regulation and control units and the deviation distribution strategy between the network regulation and direct regulation units.

[0028] 1. Deviation allocation strategy for network-provincial regulation and control units with priority in modifying hydropower plans

[0029] Ultra-short-term load forecast deviation, inter-grid power transmission and reception deviation, and superposition of new energy output deviation are used as the source of deviation. The intermittent power transmission and reception may deviate from the previous grid transmission and reception plan.

[0030] The formula for calculating the total deviation is: P TotalBias =P ForcastBias +P T...

Abstract

The invention relates to a scheduling plan deviation elimination and distribution method for promoting renewable energy consumption, and the method comprises the following steps: taking ultra-short-term load prediction deviation, inter-provincial power transmission and reception plan power deviation and new energy output deviation as deviation sources, and distributing the deviation to a network scheduling straight-pipe unit and a provincial scheduling straight-pipe unit in a province through a determined distribution rule; and according to the determined distribution principle, distributing the deviation of the direct regulation unit in the network direct regulation unit. The plan completion balance of each power plant on the basis of renewable energy consumption is promoted, the optimalconfiguration of resources in a province range is improved, and the safe, stable and reliable operation of power system production is ensured.

Description

technical field [0001] The invention discloses a grid-provincial coordination and water-fire coordination intraday scheduling plan deviation elimination distribution method for promoting the consumption of renewable energy in the initial stage of a power market, belonging to the field of power system automation. Background technique [0002] As an existing technology, the day-ahead active power dispatching plan is usually formulated in advance by the operation mode personnel of the power grid according to the forecast situation of the power grid on the day before the dispatching day. The actual operation of the power system is affected by various factors, such as the maintenance and failure of power transmission and distribution equipment, the modification of the shutdown plan, the short-term load forecast, the new energy output forecast, and the inter-provincial power transmission and reception plan. Based on this, the generating set cannot fully execute the power generatio...
