It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details.

The existing research on power market simulation technology comprises 'Zhoushime, wanhaining, schluhong', and the like, the development and application of a power market simulation system [ J ]. A power grid technology, 2010, 34 (1): 117-121 "and" shore liqin, managed dawn macro, peak. Implementation of a net platform based power market simulation system [ J ]. Grid technology, 2004, 28 (13): 60-64 ", initially constructing an electric power market simulation system, wherein the electric power market simulation system is still relatively short in capability of developing electric power market operation experiments of multiple cycles, multiple market varieties and multiple energy coupling from the aspects of economic operation and physical operation in an electric power market environment. Most of the existing electric power market simulation systems only carry out scene simulation experiments on physical models of existing electric power grids, and the property of the power generation type in the electric power grid models cannot be changed, so that the existing electric power market simulation systems are limited to simulation of bidding processes for a single time period and a single scene, and the requirements of long-period and multi-scene deduction and verification evaluation under a novel electric power system are difficult to support.
Referring to fig. 1, the method for constructing a power grid base model of a novel power system according to the embodiment of the present invention includes the following steps:
s1, reading current power grid model data to screen generator sets, classifying the types of the screened generator sets, and calculating the proportion of installed capacity of each type of generator set to the total installed capacity of all the generator sets;
s2, setting a target installed proportion of the new energy unit on the basis of the proportion of the installed capacity of each type of generator unit to the total installed capacity of all the generator units, and converting the traditional energy unit into the new energy unit to generate a target generator unit capacity model;
and S3, configuring the standardized parameters of the generator sets in batch aiming at the generated target generator set capacity model, and carrying out network modeling configuration on the newly added new energy source generator set to complete the construction of the power grid basic model.
In a possible implementation, step S1 specifically includes:
s1.1, quickly screening generator set information;
the power grid model data is a set of all equipment elements and line data in the power grid, and the generator data comprises a plurality of sub-types such as unit id, unit name, station to which the generator belongs, connection point number, rated capacity, rated voltage, rated capacity, generator type, commissioning state and the like, and the data scale is large and complex. Part of the generator sets are not in an operating state due to the problems of failure, maintenance, debugging and the like; due to factors such as power grid line optimization, a part of generator sets do not have connection point numbers in power grid topology. Therefore, there is a need for rapid screening of genset data. According to the embodiment of the invention, the generator sets in the running state and the connection point number existing in the connection point number are quickly screened out by traversing and associating the id, the running state and the connection point number of the generator.
S1.2, counting the type installed capacity of the generator set;
after the operation of step S1.1 is completed, the sorted units need to be classified according to generator type. According to the embodiment of the invention, the screened generator sets are quickly traversed according to the generation type attribute data of the generator sets, classified into thermal power generating sets, gas generating sets, hydroelectric generating sets, combined cycle sets, wind generating sets, photovoltaic generating sets and the like, the rated capacity data of all the generator sets are correlated, and the ratio of the total installed capacity of each type of generator set to the installed capacity of all the generator sets is calculated.
In a possible implementation manner, step S2 specifically includes:
s2.1, setting a target installation proportion of the new energy unit;
according to the embodiment of the invention, the target new energy source unit A installation proportion lambda of the power grid is set according to the scene requirement deduced by the power market simulation, and the type new energy source units (A) such as a wind turbine generator set, a photovoltaic generator set and the like can be further set 1 ,A 2 ,…,A n ) The installed proportion of each type of new energy unit, and the installed proportion lambda of each type of new energy unit i The sum is equal to the proportion of the set target new energy machine assembling machine, and the formula (1) is as follows:
s2.2, generating a generator set capacity model of the target power grid;
traversing the set B of the traditional energy type by taking the new energy installation proportion set in the step S2.1 as a target, and connecting the set B of the traditional energy type i Sorting the service time t from long to short and the installed capacity p from small to large according to the following formula (2):
preferentially selecting the traditional type unit with long service time and small installed capacity for type conversion, wherein the target type of the conversion is according to the target installed proportion lambda of each new energy type set in the step S2.1 i Distributing, and converting each traditional energy type unit into the installed capacity p of a new energy unit a The generation formula is shown as formula (3):
p a ＝σp b (3)
in the formula, σ is the installed capacity coefficient of the conversion from the traditional energy unit to the new energy unit. Because the traditional energy source unit can provide stable power generation capacity, the new energy source unit is greatly influenced by weather, and the power generation scale is random, the installation scale of the new energy source unit needs to be enlarged to ensure that the new energy source unit can provide the same power generation capacity as the traditional energy source unit.
The target of the power generation type conversion is to satisfy the conditional constraint shown in equation (4):
in the formula: p 0A Total installed capacity of new energy, P, for the initial grid model 0∑ For the total capacity of the generator assembly machine of the initial grid model,
is the total installed capacity of the wind turbine of the initial power grid model,
installed total capacity, m, of a photovoltaic unit as an initial grid model 1 Number of units, m, required to be converted from conventional energy units to wind-powered units 2 The number of the units which need to be converted from the traditional energy unit to the photovoltaic unit is m, and the number of the units which need to be converted from the traditional energy unit to the new energy unit is m.
When the constraint of the three inequalities in the formula (4) is not satisfied, the embodiment of the invention sequentially traverses the units in the traditional type energy unit set B according to the formula (2), and sequentially performs the conversion in the formula (3) until the constraint condition is satisfied.
In the step S2.2, the traditional energy source units are preferentially sorted according to the operation time and installed capacity in the process of selecting the traditional energy source units to be converted into the new energy source units, and the units are preferentially selected according to the sorting to perform power generation type conversion, so that the power generation efficiency of the units with longer operation time is reduced, and the early construction cost of the large-capacity units is greatly consumed, and therefore, the processing mode of the embodiment of the invention is more suitable for the economic benefit maximization target of the actual power grid scale evolution. The power generation type conversion can be randomly carried out in the traditional energy unit without sequencing, but the method breaks away from the development rule of the power grid scale.
In a possible implementation, step S3 specifically includes:
s3.1, configuring standard parameters of the new energy unit;
the embodiment of the invention provides a standardized parameter configuration pool of various types of new energy generator sets, standardized parameters of each type of new energy generator can be configured in the standardized parameter configuration pool, and the configured standardized parameter types can comprise: installed capacity, maximum output coefficient, minimum output coefficient, climbing coefficient, landslide coefficient, service power consumption, minimum shutdown time, minimum startup time and the like. In the standardized parameter configuration pool, a plurality of standardized parameter templates can be set for each type of new energy source unit.
S3.2, newly adding standard parameters of the new energy unit model for batch setting;
