In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
The following detailed description of the principles of the invention is provided in connection with the accompanying drawings.
Example 1
The embodiment of the invention provides a power grid enterprise comprehensive performance evaluation method based on a system dynamics theory, wherein the evaluation process is shown in a figure 1 and comprises the following steps:
(1) the method comprises the steps of obtaining a dynamic model of power grid enterprise investment operation, wherein the dynamic model is constructed on the basis of a system dynamics theory and a power grid enterprise comprehensive performance evaluation index system and comprises a plurality of index calculation modules;

(3) assigning points to the indexes based on the index values of the indexes and a preset assigning rule to obtain assigning values of the indexes;
(4) calculating the weight of each index by using an analytic hierarchy process;
(5) and (4) integrating the assigned values and the weights of the indexes, calculating the comprehensive performance of the power grid enterprise, and finishing the comprehensive performance evaluation of the power grid enterprise.
In a specific implementation process, firstly, a power grid enterprise comprehensive performance evaluation index system needs to be constructed, as shown in fig. 2. The index system is divided into three layers: the first layer is a target layer, namely a comprehensive performance index of the power grid enterprise; the second layer is a category layer and comprises a fund raising index, an economic benefit index, a reliability index, a social responsibility index and a user satisfaction index; the third layer is an index layer and comprises investment capacity, return on investment, enterprise income, capacity-to-load ratio, employment post number providing, ecological construction, electricity price and service quality.
Further, according to the requirements of the established comprehensive performance evaluation index system of the power grid enterprise, the dynamic model is divided into five modules which are a fund raising module, an economic benefit module, a reliability module, a social responsibility module and a user satisfaction module, and the method specifically comprises the following steps:
(a) fund raising module
The fund raising index takes the investment capacity of a power grid enterprise as a judgment standard and comprises three parts of own fund, loan fund and balance account investment. Wherein, the self-owned fund is determined by the income of the power grid enterprise in the last year and the distribution proportion thereof; the loan fund is determined by the existing fund and the asset liability rate of the power grid enterprise; the balance account investment is determined by the revenue of the balance account. According to the price pricing method of the power transmission and distribution, the government checks the price of the power transmission and distribution before a supervision period, and takes 3 years as the supervision period. And in the supervision period, once the approved power transmission and distribution price is higher than the policy value of the power transmission and distribution price, surplus funds can be generated in the balance account, and the surplus funds are used for the power grid investment in the next supervision period.
The investment capacity index of the power grid enterprise is calculated as follows:
I＝Iown+Iloan+Ibal
Iown＝L·rown

L＝D·h·rm·ptr+D·h·(1-rm)·pd
In the formula: l is the grid revenue and D is the power demand; h is the maximum load utilization hours; r ismIs the marketization rate; p is a radical oftrFor power transmission and distribution rates; p is a radical ofdThe price difference is purchased and sold.
Meanwhile, as the power grid construction project has the characteristics of large scale and long period, the investment benefit return evaluation of the construction project under the market environment is very important. The return on investment in the t year is:

and scoring the performance of the return on investment.
(c) Reliability module
The power grid capacity-load ratio is a key index for reflecting the power supply capacity of a power grid and evaluating the power supply reliability of the power grid, and is a ratio of the total rated capacity of power grid enterprise equipment to the maximum load of the power grid. The definition is as follows:
Figure BDA0002977676120000065
Cr(t)＝C(t-1)·rre
D(t)＝D(t-1)·ra

(d) Social responsibility module
Employment posts provided by power grid enterprises and investment in the aspect of ecological environment are used for evaluating the social responsibility completion condition of the enterprises. The method comprises the following specific steps:
Figure BDA0002977676120000066
Ic＝I·kpc
in the formula: r is a social responsibility index; j is the number of employment posts provided by the power grid company;

(e) User satisfaction module
The user satisfaction index is an important module for evaluating the comprehensive benefits of the power grid, and mainly comprises strong willingness of power consumers to reduce power consumption cost and expectations for improving service quality of power grid companies. The method comprises the following specific steps:
Figure BDA0002977676120000071
Is＝I·kps
in the formula: s is a user satisfaction index; p is the electricity price;
Figure BDA0002977676120000072

scoring the performance of the quality of service investment amount; k is a radical ofpAnd ksThe power price weight coefficient and the service quality weight coefficient; k is a radical ofpsThe investment for improving the service quality is the ratio.
In a specific implementation manner of the embodiment of the present invention, as shown in fig. 3, when a dynamic model of the investment operation of the power grid enterprise is specifically constructed, causal time sequence relationships among five modules are used as a basis. After new electricity is changed, the cost and income of a power grid enterprise are influenced, the investment capacity of the power grid is directly influenced, namely the grading of a fund raising index finally influences the comprehensive performance of the power grid enterprise, the comprehensive performance evaluation of the power grid enterprise also influences the income of the power grid enterprise, and a closed-loop feedback relationship is formed. Meanwhile, after the income and the investment capacity of the power grid are changed, the investment plan of the power grid enterprise in the aspects of ecological construction and service quality is also changed, so that the social responsibility index and the satisfaction index of the power consumer are influenced, the comprehensive benefit of the power grid is further influenced by the change of the social responsibility index and the satisfaction index of the power consumer, and a closed-loop feedback relationship is formed. After the investment construction of the power grid is influenced, the investment return rate and the capacity-to-load ratio index of the power grid are changed, so that the economic benefit index and the reliability index are changed, the comprehensive benefit of the power grid is influenced finally, and a closed loop feedback relationship is formed. Therefore, the comprehensive performance of the power grid enterprise and the evaluation indexes of the five modules form a corresponding closed-loop relation and influence each other.
The dynamic model is simulated by adopting the parameters shown in the table 1, 2016 years in a base period is taken as the initial year of the simulation in the specific implementation process, the investment and operation conditions of the power grid enterprises in the 10 years after the base period are simulated, and finally the index value of each index is calculated based on the simulation result.

Index values of the indexes are obtained according to the simulation result, and the assigned values (namely, the performance values) of the indexes are further calculated according to the assigned rule. The preset assigning rule is a step function. Taking the capacity-to-load ratio as an example, the assignment rule is as follows:
