Problems solved by technology
At present, the selection of evaluation indicators for microgrid planning is limited by the expressibility of indicators and mathematical models, and it can only reflect part of the evaluation indicators from a certain side, which is one-sided.
At the same time, the uncertainty of renewable energy generation such as wind and light in the microgrid also brings problems to the objectivity and rationality of the evaluation index calculation.

The invention provides a microgrid planning scheme evaluation index calculation method and device. The method comprises the steps of: acquiring environmental information of a place where a microgrid is located and load power information of the microgrid; acquiring power generation information of a fan of the microgrid and photovoltaic power generation information based on the environmental information; setting a time initial value and an energy storage state initial value of energy storage equipment of the microgrid; based on the power generation information of the fan, the photovoltaic power generation information, the load power information and the energy storage state initial value of the energy storage equipment, calculating characteristic parameters at a preset moment; and calculating an energy storage state parameter value at a preset moment according to the characteristic parameters, and determining an evaluation parameter for evaluating the microgrid based on the energy storage state parameter value and the characteristic parameters. According to the method, the operation characteristics of wind, light and energy storage equipment in the microgrid are fully considered, and the influence of uncertainty of wind power generation and photovoltaic power generation on evaluation index calculation is overcome, so that a reasonable reference basis is provided for a decision maker.
Description
technical field [0001] The invention belongs to the technical field of micro-grid planning, and in particular relates to a method and a device for calculating an evaluation index of a micro-grid planning scheme. Background technique [0002] A microgrid is a small power generation and power supply system composed of distributed power sources, energy storage, loads, and monitoring and protection devices. Microgrid has good performance advantages in many aspects such as renewable energy utilization, energy saving and emission reduction, and improvement of power supply reliability. The rationality of the micro-grid planning scheme is crucial to the effectiveness of the construction and operation of the micro-grid, and is the key link to determine whether the micro-grid can exert economic, social and environmental benefits. At present, the selection of evaluation indicators for microgrid planning is limited by the expressibility of indicators and mathematical models, and it can...
