Embodiment
[0056] The invention provides a method for comparing the equivalent annual cost of photothermal power generation and energy storage plus photovoltaic power generation. The specific steps are as follows:
[0057] (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, energy storage cost and other technical parameters of each province, as shown in Table 1 Show.
[0058] Table 1 Construction cost parameters
[0059]
[0060] (2) For solar thermal power generation, energy storage plus photovoltaic power generation, under the same constraint of new energy power generation, the photovoltaic power generation scale and energy storage time required for the energy storage power station are obtained. The calculation results are shown in Table 2.
[0061] It can be seen that: 1) 1 million kilowatts of...

The invention provides an equivalent annual cost comparison method, system and equipment for new energy power generation and a storage medium. The method comprises the steps of giving a photo-thermal scale, simulating annual production, and calculating a system operation index, a new energy power generation amount, coal consumption and a new energy power abandoning rate; energy storage power stations with the same installation scale are adopted to replace photo-thermal power generation, and the optimal energy storage duration of the energy storage power stations and the photovoltaic power generation scale needing to be configured are stored according to annual production simulation and annual cost; calculating annual cost of photo-thermal power generation; whether photo-thermal power generation and energy storage and photovoltaic power generation meet economic requirements or not is judged according to the difference between the annual cost of photo-thermal power generation and the annual cost of energy storage power station and photovoltaic power generation, if yes, a calculation result is output, and power system planning and operation scheduling are carried out according to the calculation result. By adopting the method, the annual cost of photo-thermal power generation, photovoltaic power generation and energy storage can be comprehensively evaluated with the goal of maximizing the economic benefits of the system and citizens, and a reference is provided for reasonably developing photovoltaic power generation, electrochemical energy storage and photo-thermal power generation.
Description
technical field [0001] The invention relates to the field of power system planning and operation scheduling, in particular to a method, system, equipment and storage medium for comparing the equivalent annual cost of new energy power generation. 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. CSP is equivalent to photovoltaic power generation equipped with energy storage. In this case, the comparison between solar thermal power generation and photovoltaic power generation plus...
