With the fast development of society, the electrical energy demands for meeting work, agricultural production and Family needs are increasing, and excessive
Exploitation has caused that conventional fossil energy is petered out and environmental pollution is increasingly serious, and various new energy is all being developed in countries in the world
Source, and will all develop a developing long-term strategy of the new energy as country, especially in the country such as Germany and Denmark, new energy is
The very big ratio of energy resource system is accounted for, China is also unwilling to be lag behind, and is greatly developing various clean energy resourcies and renewable energy power generation
Technology, country is by incentives, the development of make greater efforts to promote new energy technology and product such as subsidies.Regenerative resource, cleaning energy
The miniaturizations such as source, modularization, distributing, it is arranged near user as the compact electrical generating systems of customer power supply are built all over the world
If or in Program Construction, regenerative resource and clean energy resource distributed generation technology are provided the user by being connected with bulk power grid
Stabilization, the supply of reliable electric energy, and the energy off-grid operation in bulk power grid failure, it is ensured that the continuity of power supply and electric energy high
Quality.
The regenerative resources such as solar energy power generating with its it is inexhaustible the characteristics of, receive extensive concern.
With the development of distributed power generation, micro-capacitance sensor and energy internet, the shared ratio in microgrid of distributed photovoltaic power generation
More come also high.But the shortcomings of there is randomness and fluctuation in independent photovoltaic generating system, when it permeates in micro-grid system
When rate is larger, the safe and stable operation of micro-capacitance sensor will be influenceed.In order to solve the micro-grid system of photovoltaic generation and energy storage composition
In power-balance, stability and the problems such as the quality of power supply, it is necessary to be equipped with the more stable energy-storage system of power output, and according to
Predetermined control strategy, realizes the equilibrium,transient of micro-grid system internal energy, realizes the stable operation of photovoltaic energy storage micro-capacitance sensor.
Micro-capacitance sensor be typically by distributed power generation power supply, energy storage device, energy converter, associated loadings, monitoring system,
The small-sized electric system of the compositions such as protection system, power transmitting device, can realize self-contr ol, protection and manage.Micro- electricity
Net can both access it is local by power distribution network and with large-scale power grid parallel running, form a combined operation system, also can be independent
Ground provides electricity needs for local load, substantially increases the power supply reliability of load side, and micro-capacitance sensor accesses power network by single-point,
Influence of the small-power distributed power source access to traditional power network can be reduced.Additionally, micro-capacitance sensor will be scattered, different types of small
Type energy source combines power supply, effectively avoids abandoning optical phenomenon.
In recent years, with the development of the technologies such as wind-power electricity generation, solar energy power generating so that renewable energy power generation is obtained
Increasing utilization, technology that renewable energy power generation is combined with micro-capacitance sensor form, be complexity it is higher, using preceding
The broader technology of scape, becomes the frontier of power system research.
At present, existing micro-grid system is generally simple by the distributed power source of single kind, load, power transmitting device
Composition.Such as photovoltaic power plant, wind park etc..
The Demand-side such as industrial enterprise and family is alleviated in the urgent need to reliable and stable and economic multi-source complementary function system
Energy shortage and economy problem, especially under conditions of Peak-valley TOU power price, in order to more effectively utilize electric energy, improve electricity
The comprehensive utilization ratio of energy, while be also that the cost of electric energy is saved in Demand-side family, industrial and mining enterprises and industrial park, it is enough by being equipped with
The energy storage device of capacity, realizes the Time-spatial diversion of electric energy, and battery is charged in paddy valency, and in Critical Peak Pricing, uses storage
Can generate electricity, the reduction of electricity price can be realized.The light storage integral system that this patent is proposed efficiently solves this problem.
The content of the invention
The present invention proposes a kind of integrated micro-grid system of the storage of the light based on Peak-valley TOU power price for being applied to Demand-side,
Under conditions of Peak-valley TOU power price, main micro-capacitance sensor operating scheme and photovoltaic generation scale profit that comprehensive analysis presently, there are
With the problem for existing, the load curve of side user, reasonably configures the capacity and energy storage system capacity of photovoltaic generation according to demand,
Realize whole applications of photovoltaic power generation quantity, it is to avoid abandon optical phenomenon, while rationally utilizing electricity price between peak and valley, reduce electric cost.This
Invention is reasonable in design, and energy utilization rate is high, complete soft and hardware system, is easy to large-scale promotion.
