Time sequence simulation method for making monthly electric energy transaction plan in consideration of various energy sources

Abstract

The invention discloses a time sequence simulation method for making a monthly electric energy transaction plan in consideration of multiple energy sources, belongs to the technical field of monthly electric energy transaction plan making of an electric power system, and comprises the following steps of: firstly, establishing a monthly electric energy transaction plan modeling strategy according to the actual demand of the monthly electric energy transaction plan: proposing a monthly electric energy transaction plan modeling method and constructing a monthly electric energy transaction plan model structure; secondly, modeling each part of the model according to an established monthly electric energy transaction plan modeling strategy: a plan monthly model cost function part, a plan monthlymodel constraint condition part, a subsequent monthly model cost function part, a subsequent monthly model constraint condition part and a whole-year electric energy production fair constraint part;and finally, optimizing and solving the model to obtain a final monthly electric energy transaction plan. The time sequence simulation method is introduced into monthly electric energy transaction plan making, staged modeling is carried out according to plan months and subsequent months, and finally a monthly electric energy transaction plan model capable of guaranteeing feasibility and fairness is obtained.

Description

technical field [0001] The invention belongs to the technical field of formulation of monthly electric energy transaction plans in electric power systems, and relates to a time series simulation method for formulation of monthly electric energy transaction plans considering multiple energy sources. Background technique [0002] When formulating the power generation plan, the power trading center first formulates the annual contract power plan based on the electricity purchase and sale contract transaction power of each power generation company and the planned power issued by the state, and then gradually subdivides it into monthly power trading plan and daily dispatch plan according to the time scale, and finally Instruct the power generation unit to produce electricity in the form of a 96-point power regulation curve. Among them, the monthly power trading plan is an intermediate link between the annual contract power plan and the daily dispatch power generation plan, and pl...

Problems solved by technology

However, due to the disturbance effect of new energy grid connection on the thermal power generation plan, the risk that the annual planned power generation of thermal power units cannot be completed increases, and the fairness limit of the annual base power completion rate deviation is difficult to meet

To sum up, under the background of large-scale grid-connected new energy, the monthly power trading plan should not only ensure the fairness of power production from the perspective of annual contract power, but also consider the feasibility of implementing the daily dispatch plan, which is a long-term dynamic. The optimization problem has many influencing factors, and the model is complex and difficult to solve. The existing monthly power trading plan formulation method cannot solve it
