Embodiment Construction
[0023] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the examples in this application, all other implementations obtained by those of ordinary skill in the art without creative work fall within the scope of protection of this application.
[0024] The capacity retention (hoarding) of electricity is a common method used by power generators to use market power. You can increase the price away from the cost to obtain additional profit. The power capacity retention behavior of power generators is not only highly harmful, but also highly concealed, that is, it is not easy to be detected by the outside world. Therefore, how to timely detect whether the generators have capacity retention behavior has b...

The present application discloses a method, device and equipment for detecting power capacity retention. In this method, firstly obtain the electric energy declaration data and the frequency regulation auxiliary service declaration data; determine whether the electric energy declaration data and the frequency regulation auxiliary service declaration data are abnormal; if the electric energy declaration data or the frequency regulation auxiliary declaration data is abnormal, the decision model based on the declared capacity is determined. For the first power purchase cost, the second power purchase cost is determined based on the non-declared capacity decision model; if the difference between the first power purchase cost and the second power purchase cost is greater than or equal to a preset threshold, it is determined that there is power capacity retention. Due to the highly coupled relationship between electric energy and frequency regulation ancillary services, comprehensive analysis based on electric energy and frequency regulation ancillary services can help to detect whether there is a capacity retention problem in power generators in a timely and effective manner.
Description
technical field [0001] The present application relates to the field of electric power technology, and in particular, to a method, device and equipment for detecting power capacity retention. Background technique [0002] With the reform of the power industry, the power industry has gradually shifted from the traditional monopoly operation to the competitive market-oriented operation, so as to achieve the optimal allocation of resources through competition and improve the production efficiency of the power industry. [0003] In the context of electricity marketization, the government or regulatory agencies no longer guarantee the recovery of power generation investment and a reasonable return on investment, and accordingly, power generators no longer assume the responsibility for ensuring sufficient power supply. Therefore, in order to obtain higher profits, power generators may have behaviors such as capacity retention, for example, deliberately arranging maintenance or shut...
