Method for analyzing economic performance of shore power operation

Abstract

The invention discloses a method for analyzing economic performance of shore power operation and belongs to the field of economic performance analysis methods. At present, via conventional analysis ofeconomic performance of shore power operation, a reasonable price for shore power use cannot be obtained, and the conventional analysis is low in credibility. The method disclosed in the present invention includes the following steps: 1. according to a structure of a high-voltage shore power system, an economic model is established via quantification of parameter indexes; cost of a port and shipusers, benefits after shore power transformation and the number of years needed for the cost recovery are determined; 2. Models are built; a port cost recovery time model, a model for comparing costsof a ship before and after transformation of the ship's shore power, and a ship cost recovery time model are built; 3. for the established mathematical models, a reasonable shore power utilization price is found according to a relationship between state subsidies and the port and the ship, as well as effect of shore power service fees and berth utilization rates on cost recovery time after appropriate model data is chosen; port cost recovery time and the ship cost recovery time are enabled to be minimized at the same time, and popularization of use of shore power can be facilitated.

Description

technical field [0001] The present invention relates to a method for analyzing operation economy, in particular to a method for analyzing shore power operation economy. Background technique [0002] In recent years, with the continuous and rapid development of the national economy, the pace of port construction has become faster and faster, and the number and density of ships berthing at the wharf have increased significantly, which consumes a lot of energy and brings huge pollution. In contrast, replacing the traditional self-provided fuel engine generator power supply with port grid power supply has significant advantages. It can not only save the cost of power supply for ships in port, directly save the maintenance cost of the ship's own power generation facilities, but also improve the quality of the crew's living and working environment. It can also improve the energy efficiency of the port and effectively reduce the environmental pollution of the port. However, at the...

Problems solved by technology

However, at the same time, the shore power project also has low system applicability and poor reliability. The berth scheduling mechanism is not perfect and the utilization rate of shore power is low. The enthusiasm for the use of shore power is not high

[0003] On the one hand, the economic analysis of shore power operation is complicated, with a large amount of data, complicated calculation, long calculation time, low efficiency, and the obtained results are inaccurate, not intuitive, and have low credibility, which cannot fully demonstrate the feasibility of shore power operation Waiting question

On the other hand, there is still the problem that the power supply unit is difficult to choose a reasonable price for the use of shore power, and the recovery period of the port and the cost-effective recovery period of the ship cannot be achieved at the same time, which is not conducive to the promotion of the use of shore power.
