Micro-grid distribution type new energy storage system

Abstract

A micro-grid distribution type new energy storage system is composed of a distribution type new energy power generating system, a distribution type energy storage platform, a load energy-saving system and an energy management system. According to the micro-grid distribution type new energy storage system, the distribution type energy storage platform is used as an energy buffering core platform to reasonably coordinate the relationships between distribution type power generation, distribution type energy storage, power load and traditional power, and the purposes of maximizing the distribution type power generation, optimizing the service life of the distribution type energy storage, saving the power load to the largest extent, and minimizing the traditional power are achieved. Power consumption of the power using side is substantially lowered, immature and unstable large-scale energy storage power stations are converted to the mature and stable micro-grid distribution type new energy storage system distributed in a plurality of areas or buildings in a city, power utilization pressure is quickly relieved, energy is saved, emission is reduced, investment cost is lowered, and the requirement for electricity safety of a single user is met.

Description

technical field [0001] The invention relates to a micro-grid distributed new energy storage system mainly applied to urban buildings, parks, communities and other buildings. Background technique [0002] Urban economic development has caused a series of social problems, such as population growth, energy crisis, environmental pollution, natural disasters, etc. Among them, the shortage of urban electricity is particularly serious. [0003] The problem of urban electricity consumption is manifested in the following aspects: urban electricity shortage, large-scale power outages and power shortages, high carbon emissions; mismatch between planned electricity consumption and power generation, and uneven electricity load periods, resulting in contradictions between supply and demand and resources. Waste; the proportion of new energy applications is low, such as the low proportion of wind energy and solar energy connected to the grid, while the consumption of the grid is lower, and ...

AI Technical Summary

Problems solved by technology

[0005] One is to build a thermal power station: large investment, high energy consumption, unsustainable development, causing new pollution and social problems; a 1000MW thermal power station, the construction cost is about 3.5 billion yuan, and the daily water consumption is about 100,000 tons; in 2010 National thermal power plants consume about 60 million tons of standard coal

[0006] The second is to build pumped storage power stations: high requirements for water resources and topography; ecological damage: intensified water erosion below the dam, changes in rivers and negative impacts on animals and plants; in areas with large changes in precipitation seasons, power generation in dry seasons The amount of power generation is small or even stopped; the investment in infrastructure construction is large, with a one-time investment of more than several billion yuan, and even damming and resettlement are required; the construction period is long
