Regional available solar energy resource evaluation method

Abstract

A regional available solar energy resource evaluation method comprises the following steps: collecting basic data of a to-be-evaluated region; quantizing everyday available solar energy radiant quantity in the region; quantizing photovoltaic optimal allocation quantity in the region. The regional available solar energy resource evaluation method can calculate everyday available solar energy radiant quantity in the region according to regional geography weather information like longitude and latitude and sunlight intensity; the method then considers regional photovoltaic construction land occupation conditions in the region according to the everyday available solar energy radiant quantity, thus using economical purpose to determine the best photovoltaic installed capacity. The calculation evaluation method and analysis evaluation system can ensure the installed photovoltaic to maximumly fully utilize everyday available solar energy radiant quantity in the region to generate power, thus preventing investment waste caused by idle photovoltaic after excessive construction of photovoltaic capacity, and providing planning suggestions for regional grid and power source construction.

Description

technical field [0001] The invention belongs to the technical field of computer control, in particular to a method for evaluating regional available solar energy resources. Background technique [0002] In recent years, a new round of energy revolution centered on electricity has kicked off, with the aim of realizing low-carbon energy with smart grid as the core. Active intelligent power distribution systems that can effectively accommodate distributed renewable energy generation and have active management, active control, and active service capabilities are the main direction for the development of modern power distribution systems. Realizing the effective analysis and evaluation of the availability level of regional distributed solar energy resources is a basic task in the planning and design of active power distribution systems. [0003] For any planning area, the available solar resources in this area are limited, and if the installed capacity of photovoltaics exceeds t...

Problems solved by technology

Regional solar resource assessment studies in the field of meteorology often focus on the modeling of solar resource influencing factors. The results have important guiding significance for the construction of photovoltaic power stations, but they cannot be directly applied to the active distribution network planning for distributed energy consumption; In the field of power system planning, the determination of planned photovoltaic capacity is often only considered from the technical constraints of grid operation and the benefits brought by photovoltaic power generation, ignoring the constraints of solar resources on the available installed capacity of photovoltaics.

The separation of the two will inevitably result in waste of investment or inability to fully utilize clean energy
