Method for constructing distributed power supply smart grid with hierarchy structure

Abstract

The invention discloses a method for constructing a distributed power supply smart grid with a hierarchy structure. The construction of the grid adopts a parameter measurement module, a grid node parameter two-way intelligent communication module, an information processing, management and control module, an intelligent scheduling driving module, a distributed energy source access module, an intelligent regulation load output module, and a battery pack consisting of a plurality of groups of single-group controllable batteries to form unit systems of the distributed power supply smart grid withthe hierarchy structure, wherein a unit system of a bottom layer is connected with a unit system of the same layer or an upper layer to form the distributed power supply smart grid with the hierarchystructure. The distributed power supply smart grid has the advantages of having self-cure, real-time monitoring and measurement scheduling, exciting users, resisting attacks, allowing accesses, interconnections and inter-supplies in various power generation forms such as a new energy source and the like; and in the smart grid, a user can turn from a guest into a host to become a power supplier toensure that the electric power generated by a solar energy electroplate on a user roof is transmitted to a grid for centralized distribution so as to create values for the user.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a method for constructing a distributed power smart grid with a hierarchical structure. technical background [0002] Recently, as one of the national strategic developments of various countries, the smart grid has been sought after by the world. Looking at the existing information, we can see that the so-called "smart grid", as the name suggests, refers to a new type of grid that has become smarter, knowing how to acquire and distribute electricity more "smartly". The fusion of distributed, integrated, high-speed two-way communication network and distributed, interactive multi-source power node network is the magic weapon of its "superior intelligence". With its advanced sensing and measurement technology, equipment technology, control method and decision support system technology, it has created a reliable, safe, economical, efficient, environmentally friendly and safe sma...

Problems solved by technology

[0010] Since the smart meter is based on the existing power supply system, coupled with the limitations and deficiencies of the existing technology and products, this power supply method based on the existing power grid is intelligently powered through a centralized management mode, although it can achieve fine Smart power supply and guide users to understand the cost-effective use of electricity, so that the effect of the smart grid realized is very limited, and many advantages of the smart grid and technology have not yet been realized

For the existing power grid, it is difficult for users to freely access clean energy such as wind power and solar power, and it is even more difficult to complete intelligent real-time deployment of power supply and power consumption plans, and the integration of distributed power generation (DER) with the existing power grid. Only with the participation of existing power suppliers, it is difficult to get rid of the shackles of the above-mentioned model, and it is difficult to make breakthroughs. For example, solar and wind power generation is affected by natural conditions, and the power output is discontinuous and extremely unstable. To solve this problem, The power plant must spend a lot of investment in power storage and inverter power transmission, and the effect is not ideal, causing a lot of waste, and cannot maximize the investment benefits of clean energy, and cannot achieve the effect of motivating users
