Device for monitoring early load condition of micro-grid

Abstract

The invention discloses a device for monitoring the early load condition of a micro-grid. The device comprises a portable box. A control module and a current measuring clamp are disposed inside and outside the portable box respectively. A through hole is formed in the portable box. The cable of the current measuring clamp passes through the through hole to be connected to the control module. In addition, the device also includes a conditioning circuit between the current measuring clamp and the control module. The device for monitoring the early load condition of a micro-grid acquires the loadpower data, contributes to the subsequent reasonable regulation and control of load-side energy of grid operation, stores related energy and configures new energy, and reduces unnecessary configuration waste as much as possible.

Description

technical field [0001] The invention relates to the field of new energy technologies, in particular to a device for monitoring early load conditions of a microgrid. Background technique [0002] With the development of society, the new energy industry has gradually gained attention. Due to the instability and uncertainty of new energy, as well as the impact of weather, the power generation fluctuates significantly, which affects the balance of the entire power grid. Therefore, large-scale The construction of new energy power plants is limited. In this case, distributed power generation and smart microgrid make up for the above shortcomings. The so-called smart microgrid is a small grid and microgrid composed of power generation system, energy storage system, and load. It has the characteristics of high-speed adjustment of supply and demand balance, grid-connected and off-grid fast switching. Among them, the power generation system: wind power generators, mainly photovoltaic...

Problems solved by technology

[0003] Since the characteristic of the microgrid is that its new energy and load are in a balanced state in most cases, so in the initial stage of microgrid construction, regarding the on-site load power consumption, load fluctuations over a period of time, and long-term use The detection of electricity habits plays a vital role in the configuration of all aspects of the entire microgrid. If the load is estimated too large in the early stage, the configured energy storage capacity is too large, and the price of energy storage is relatively high, which will lead to a waste of a lot of resources; if The load is expected to be too small, and the configuration of small energy storage will lead to limited energy in the microgrid in some special cases, which will not be able to provide energy to the load, resulting in the disconnection of the microgrid
