Day-ahead power generation plan compilation method of bilateral transaction and apparatus thereof

Abstract

The invention relates to a day-ahead power generation plan compilation method of bilateral transaction and an apparatus thereof. The method comprises the following steps of constructing a day-ahead power generation plan target function; using the day-ahead power generation plan target function to configure planned electrical output and / or transaction electrical output of each unit; and based on the planned electrical output and / or the transaction electrical output of each unit, compiling a power generation plan. By using the method and the apparatus, based on a unit start stop plan, minimum total cost of a system and a minimum deviation value of different component electric quantities are taken as an object and one group of optimal unit output plan is determined so as to satisfy a system load and a standby demand and simultaneously satisfy constraints of an upper limit / a lower limit of the unit output, a climbing rate / a landslide rate, a power transmission equipment conveying capability and the like; and safe and economic operation of a power grid and coordination unification of different component electric quantity execution can be guaranteed.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a method and device for preparing a day-ahead power generation plan for bilateral transactions. Background technique [0002] At present, dispatching agencies at all levels carry out power generation dispatching work based on the "three public" dispatching principles aiming at the balanced completion of government plans. Although some areas have launched direct purchases of electricity for large users, the total amount of direct purchases of electricity is relatively small. The achievement of the goal has little effect. The "three public" dispatching and control goals are clear and single, with strong operability and guidance, and are the yardstick for the actual work of dispatching agencies at all levels. [0003] The liberalization of bilateral transactions and the expansion of transaction scale have posed serious challenges to the current scheduling transaction mechanism and opti...

Problems solved by technology

[0008] With the gradual increase in the proportion of bilateral traded electricity, the number of traded varieties has gradually increased, the frequency of transactions has continued to increase, and the scope of transactions has continued to expand. The market-oriented characteristics of power supply have gradually emerged. Due to the incomplete market structure in the initial stage of market-oriented construction, there is a lack of market-oriented power balance. Mechanism, the existing planning and scheduling method with annual balance and rolling adjustment as the core has been difficult to meet the requirements of marketization
