Regional regulation and control interaction terminal and method for distributed photovoltaic

Abstract

The invention provides a regional regulation and control interaction terminal and method for distributed photovoltaic. The regional regulation and control interaction terminal comprises a communication unit, a man-machine interaction unit, a main control unit, a storage unit and a master station server at a dispatching center, and is characterized in that the master station server at the dispatching center receives power utilization information of a distributed photovoltaic power station, an interaction will of the distributed photovoltaic power station and various interaction amounts declared by the distributed photovoltaic power station, and is also used for issuing interaction time periods and peak-valley electricity prices; the man-machine interaction unit is used for displaying the interaction time periods and the power utilization information of the distributed photovoltaic power station, and acquiring the interaction will of the distributed photovoltaic power station; and the main control unit calculates the interaction load capacity declared by the distributed photovoltaic power station according to the interaction time periods and the peak-valley electricity prices. According to the invention, a storage user interaction terminal can meet two-way communication requirements of the regional regulation and control terminal for distributed photovoltaic and the master station server, thereby promoting distributed photovoltaic to participate in power grid interaction, and achieving the objectives of reducing the difference between peak and valley of a power distribution network and improving the running efficiency of the power distribution network.

Description

technical field [0001] The present invention relates to an interactive terminal and method, in particular to an interactive terminal and method for regional regulation of distributed photovoltaics. Background technique [0002] In the process of economic development, along with energy consumption, the resource demand structure dominated by fossil energy will damage the earth's environment, that is, the 3E problem. The way to solve the 3E problem is to rely on the development of clean energy technology to realize energy, A virtuous circle of environment and economy. Compared with fossil fuels such as coal, oil, and natural gas, solar energy is an ideal renewable green energy due to its huge energy storage capacity, ubiquity, and economy. With the issuance of the national approval authority and the promulgation of various policies, distributed power generation technology has ushered in a new round of rapid development, especially photovoltaic power generation, which has the a...

Problems solved by technology

[0004] At present, distributed photovoltaic power generation is mostly based on decentralized roofs or building integration. Based on the simplicity of wiring and the principle of local energy access and local use to reduce losses, the photovoltaic access in urban power grids will be scattered and disorderly. Yes, a large number of distributed photovoltaics have changed the original single power supply structure, and the single distribution network has become a multi-power supply structure, and it has also brought great difficulties to the dispatching work of the power grid.
