Embodiment approach

[0096] As an implementable manner, the power generation is calculated as:

[0097] Let the installed capacity of the i-th generator set be C i , The forced outage rate is q i , The power generation of the i-th generating set According to the equivalent power function E (i-l) (k) to calculate:

[0098] E G i = p i X k i - 1 + 1 k i E ( i - 1 ) ( k )

[0099] Where: p i = 1-q i ;K i-1 = X i-1 / Δx; k i =(x i-1 +C i ) / Δx.

[0100] As an implementable manner, the production cost is calculated as:

[0101] C total =C fuel +C O&M +C UEC +C envi +C tsu +C bsu +C sd

[0102] Where: C fuel Is the fuel cost; C O&M For operation and maintenance costs; C UEC Is the cost of power shortage; C envi Is the environmental cost; C tsu It is the start-up cost of the steam turbine of the thermal power unit; C bsu Is the boiler start-up cost; C sd For downtime costs.

[0103] Step C5: Correct the equivalent power function ...

Description

Technical field [0001] The present invention relates to the field of energy technology, in particular to the technical field of power system operation and control analysis and processing, in particular to a multi-region and multi-time scale new energy power large-scale development and consumption panoramic analysis and processing system and method. Background technique [0002] The use of traditional fossil energy has exacerbated environmental pollution, global warming and other issues, making new energy represented by wind power have been greatly developed in recent years. With the continuous increase of the proportion of new energy such as wind power, its normal dispatching of power grids, The impact of operation and management will also become greater. [0003] At present, the power system refers to all units including thermal power units, hydropower units, and wind power units as full-grid units. Among them, the power energy composed of thermal power units and hydropower units ...
