Embodiment
[0054] This embodiment considers mechanism evaluation in the peak shaving ancillary service market. The method for evaluating the market mechanism of peak shaving auxiliary services that takes into account both economy and environmental protection described in this embodiment includes the following steps:
[0055] Step 1: Establish the total revenue model after the unit participates in the peak shaving auxiliary service market.
[0056] In this embodiment, the unit transaction period is 15 minutes. For the fixed compensation mode, the compensation standard for under-generating electricity due to the participation of the unit in peak regulation is 50 yuan (MWh) -1 .
[0057] For a section of clearing compensation mode, unit quotations have upper and lower limit settings, and the set quotation upper limit is 400 yuan (MWh) -1 , the quotation lower limit is 0 yuan (MWh) -1 . For the two-stage clearing compensation model, it is stipulated that the quotation of the second stag...

The invention discloses a peak shaving auxiliary service market mechanism assessment method. The method comprises the following steps: step 1, establishing a total income model after a unit participates in a peak shaving auxiliary service market; step 2, scheduling targets under different compensation modes are analyzed, and a valley real-time deep peak shaving market transaction mechanism model is established; and step 3, establishing a mathematical model of unit set fuel benefits, solving transaction results and unit set fuel benefits under different compensation modes according to set unitquotations, and carrying out mechanism evaluation. On the premise of considering the economy of the unit units, the environmental friendliness of the unit units is considered at the same time, and thefuel benefits of the unit units of the thermal power generating unit in the peak shaving auxiliary service market are calculated. According to the method, the peak regulation auxiliary service markettransaction mechanism is evaluated, the result provides a theoretical basis for benefit evaluation after the thermal power generating unit participates in the peak regulation market, and meanwhile, atheoretical basis is provided for subsequent peak regulation auxiliary service market construction and other work.
Description
technical field [0001] The invention belongs to the field of electric power market in the electric power system, and relates to a method for evaluating the market mechanism of peak-shaving auxiliary service taking into account both economy and environmental protection. Background technique [0002] Peak shaving auxiliary service refers to the services provided by grid-connected generators, interruptible loads or electric energy storage devices, which can smoothly and stably adjust unit output, change unit operating status or adjust load according to grid peak shaving requirements. The trading products in the peak shaving auxiliary service market include real-time deep peak shaving, interruptible load peak shaving, electric energy storage peak shaving, thermal power shutdown backup peak shaving, thermal power emergency start-stop peak shaving, and cross-provincial peak shaving, etc. Among them, the real-time deep peak shaving transaction refers to the transaction of providing...
