Embodiment Construction
[0038] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0039] A cost-benefit economic analysis method for all parties involved in shore power construction and operation, such as figure 1 shown, including the following steps:
[0040] Step 1: Analyze the composition of the shore power system. According to the power supply process of the shore power system and the relationship between each part, analyze the construction, renovation and operation costs of each part from the economic point of view, and clarify the power grid company, port company, ship and government after using the shore power system income;
[0041] Step 2: Through the analysis from the above economic perspective, construct a cost-bene...

The invention discloses a shore power construction and operation cost effectiveness economical efficiency analysis method. The method comprises the following steps that 1, the cost of grid companies, port administrative affair companies, ships and the government and earnings obtained after all parts use shore power are analyzed from the perspective of economical efficiency according to the structure of a shore power system, the power supply process and the relation between all the parts; 2, a cost effectiveness mathematic model of the grid companies, the port administrative affair companies, the ships and the government after the shore power is used is constructed; 3, maximization of the profit of the four parties or any three parties is the aim, the optimum shore power price is calculated, marginal condition economical efficiency analysis is carried out, and the relation among the government subsidy rate, the shore power utilization hour number, the optimum shore power price and the profits of all the parties is found out. A shore power system is studied from the perspective of economics, and the characteristics of shore power of seaports, and the Yangtze River and lakes are compared from multiple prospective; on the basis of clearing the investment and benefit relation of all the parties during shore power construction and operation, reference can be provided for shore power popularization of the grid companies, the port administrative affair companies and the government.
Description
technical field [0001] The invention relates to a method for analyzing the substitution of shore power electric energy in a port, in particular to an economic analysis method for optimizing the cost and benefit of all parties involved in the construction and operation of shore power. Background technique [0002] In recent years, the huge energy consumption and air pollutant emissions caused by the use of auxiliary engines for power generation during the berthing of ships have made the work of energy conservation and emission reduction in coastal port cities increasingly urgent. The use of shore power for electrical energy replacement is widely considered to be a good solution. Most of the research on shore power at home and abroad only stays at the technical level analysis and application level introduction, and lacks the economic analysis of all parties involved in the construction and operation of the shore power system. Therefore, urgently need to solve the above-mention...
