Problems solved by technology

At the same time, the power of wind turbines is determined by the wind speed, and the power of photovoltaic power generation units is affected by light, etc., and the power change rate is relatively fast. It is difficult to formulate and implement accurate power generation plans for new energy power stations such as wind farms / photovoltaic power stations like conventional power sources, and the system needs to provide them. The fast enough peak shaving rate increases the difficulty of system peak shaving and increases the operating cost of the system

Embodiment

[0107] Assuming that there are 4 wind farms in the power grid in a certain area, wind farm 1 has an installed capacity of 100MW, wind farm 2 has an installed capacity of 60MW, wind farm 3 has an installed capacity of 120MW, and wind farm 4 has an installed capacity of 150MW. 1 ,p 2 ,p 3 and p 4 ), the order of declared on-grid electricity prices in each time period is shown in Table 1. The maximum value of grid load forecast for the next day is 640MW, and the minimum is 390MW. According to the calculation method of wind power capacity based on continuous time series, the load space that the system can use to accommodate wind power in the next day is obtained, namely Figure 7 Acceptable capacity curve of medium wind power. According to the power prediction curve of wind farms, the mathematical model of wind power participating in bidding for grid connection, and the calculation of wind power acceptance capacity, four wind farms' next-day power generation sequencing plans ca...

Abstract

The invention relates to a method for use in the technical field of new energy power generation, in particular to a method for making a power generation absorption scheme for new energy power stations based on price bidding. The method comprises the following steps: A, issuing load prediction and new energy power generation acceptance capacity of a next day; B, submitting the on-grid energy and electricity prices at the closing auction of the next day by the new energy power stations; C, sequencing the power stations according to the on-grid energy and electricity price submitted by each new energy power station, and determining power purchasing plans and electricity prices for corresponding periods of the next day; D, making power generation plans of corresponding periods according to the power purchasing plans by each new energy power station. By using the method in price bidding of new energy, the power purchasing cost in the entire period of a power generation plan is minimized, vicious competition among the new energy power stations can be avoided, and maximum absorption and economical running of new energy power generation are realized.

Description

technical field [0001] The invention relates to a method in the technical field of new energy power generation, in particular to a method for formulating a new energy power station electricity consumption plan based on bidding online. Background technique [0002] New energy operation data in recent years shows that due to the fluctuation of power supply structure and large-scale new energy power generation, large-scale abandonment of wind / solar power has occurred in the "Three North" region, and new energy power generation companies are competing for more power. The situation is more serious. At the same time, the power of wind turbines is determined by the wind speed, and the power of photovoltaic power generation units is affected by light, etc., and the power change rate is relatively fast. It is difficult to formulate and implement accurate power generation plans for new energy power stations such as wind farms / photovoltaic power stations like conventional power sources...
