Technical Field
The invention relates to the technical field of power markets, in particular to a method for sharing local depth peak regulation cost of a power grid.
Background
The peak shaving of the power grid refers to a process that a conventional generator set needs to be arranged to operate in a power interval lower than a compensated peak shaving reference or even be arranged to be stopped in order to meet the requirement of power balance during a load low-ebb period or a power generation peak period of a renewable energy source generator set. With the large-scale grid connection of renewable energy sources in recent years, the permeability of photovoltaic and wind turbine generators in a large multi-grid range is continuously improved, so that the peak load regulation demand of a power grid is continuously increased. In the foreseeable future, the installed capacity of renewable energy sources still rapidly increases, the proportion of installed machines of the heat supply unit with limited peak regulation potential in a power supply structure is continuously increased, and the peak regulation capability, particularly the low-valley peak regulation capability, of conventional units such as thermal power units is severely restricted. Therefore, the inadaptation of the power peak shaving auxiliary service requirement and the energy structure optimization direction becomes a prominent problem of safe and stable operation of the power grid and new energy consumption in a long period of time in the future, and effective management and control of various scheduling resources are urgently needed, the potential of resource optimization configuration is deeply dug, and the system peak shaving potential is deeply dug by matching with an incentive compatible mechanism design.

Local peak regulation cost generated by local regional power grid blockage is shared by the whole network market main body, so that the benefit distribution of the market main body is unbalanced. The peak regulation capability of part of power plants is strong, the peak regulation compensation income is very little, but the unnecessary allocation is born, and the market excitation effect is not fully exerted.
