Embodiment
[0080] The present invention provides a method for evaluating the benefits of solar-thermal power generation in a high-proportion new energy system. The specific steps are as follows:
[0081] (1) Read in information such as power supply planning, load forecasting, new energy power generation, daily load characteristic curve, annual load characteristic curve, solar thermal power generation cost, photovoltaic power generation cost and technical parameters of each province. Considering the changes in solar thermal and photovoltaic construction costs, three scenarios are analyzed, as shown in Table 1.
[0082] Table 1 Construction cost parameters
[0083]
[0084] (2) Given the new energy power generation consumption index of 76.6 billion kWh, carry out 8760 hours of production simulation throughout the year, and calculate the wind power installed capacity demand, photovoltaic installed capacity demand, thermal power installed capacity demand, and system coal consumption witho...

The invention provides a photo-thermal power generation benefit evaluation method, system and device and a storage medium, and the method comprises the steps: giving a new energy consumption index, and calculating the installation demands of wind power, photovoltaic and thermal power and the power supply reliability of a system under the condition of no photo-thermal power generation according to the simulation of annual production, and taking the demands as a first result; the method comprises the following steps: giving a photo-thermal power generation installation scale, keeping a new energy consumption index and power supply reliability unchanged, and calculating wind power and photovoltaic installation requirements and thermal power installation requirements according to annual production analogue simulation to serve as a first result; calculating photo-thermal power generation capacity benefits, new energy installation substitution benefits and electric quantity benefits according to the first result and the second result; the national economic net benefit of photo-thermal power generation is calculated; and judging whether the national economic net benefit of photo-thermal power generation meets the economic requirement, if so, outputting a calculation result, and determining the reasonable scale of photo-thermal power generation of the high-proportion new energy system according to the calculation result. The method aims at maximizing national economic benefits, comprehensively evaluates photo-thermal power generation benefits and cost, and determines the reasonable scale of photo-thermal power generation of the high-proportion new energy system.
Description
technical field [0001] The invention relates to the field of power system planning and operation scheduling, in particular to a method for evaluating the benefits of solar-thermal power generation in a high-proportion new energy system. Background technique [0002] From the perspective of the development prospects of the power system, the requirement for the proportion of new energy power generation will become higher and higher. Relying solely on wind power and photovoltaics to meet the proportion of new energy consumption will lead to a high rate of new energy abandonment, and it will even be impossible to complete the new energy. Consumption ratio target. Concentrating solar power (CSP, referred to as CSP) has the characteristics of cleanliness and good regulation performance. Using CSP to replace wind power and photovoltaics will result in three types of benefits: [0003] 1) Solar thermal power generation can replace part of conventional thermal power due to its adjus...
