Problems solved by technology

[0003] However, all these are small-step improvements. If the scheduling optimization is constrained by the physical power plan arranged years ago and months ago, there will inevitably be loss of efficiency and waste of resources.

Embodiment Construction

[0069] In order to facilitate the understanding of the content of this solution, further elaboration will be made below in conjunction with specific examples.

[0070] Because the inter-provincial tie-line is also a resource on the power generation side, it can be regarded as a power plant to participate in power distribution, so the power plant type in this embodiment includes the inter-provincial tie-line.

[0071] Taking the typical dry days in a province in 2016 as an example, the 24-hour load forecast curve before the typical dry days is as follows: figure 2 shown. The minimum start-up load constrained by safety and stability constraints in Kuda typical day is 6299MW, and the transmission power of the inter-provincial tie line in the day is given priority to power generation. The predicted power generation curve is as follows: image 3 shown. From this, the schedulable load curve can be calculated as Figure 4 shown. On this basis, the base load, waist load and peak ...

Abstract

The invention provides a power generation optimization scheduling method based on load partition electricity price. By dividing the dispatchable load curve into three parts: base load, waist load and peak load, different areas are divided into a large number of energy blocks, and different locations Different power prices are marked on the energy block, and then different power plants with different electricity prices fill the energy block with power generation, and finally the optimal power generation optimization scheduling result is obtained. This method enables each power plant to combine its own power generation characteristics, electricity price and electricity with its own characteristics of the load to fill the energy block corresponding to the load curve, so as to mobilize different types of power plants to use their own peak-shaving advantages to earn more profits and consciously participate in system peak-shaving , greatly relieve the system peak load pressure.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a power generation optimization scheduling method based on load partition electricity prices. Background technique [0002] The power grid is often faced with huge peak-shaving pressure during operation. In recent years, the peak-valley time-of-use electricity price method is often used to adjust from the load point of view, but there is a lack of attention to the transaction issues of the power market. The current electricity market trading model mostly adopts medium- and long-term electricity trading rules. The latest medium- and long-term trading rules propose that planned electricity should be broken down into months, centralized bidding, contract transfer, deviation assessment, emergency transactions, special transactions for pumped storage, auxiliary services, etc. Standardization and innovation, if implemented and supported by mechanisms such as the deregulation of...
