Specific implementation mode
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
As shown in Figure 1, the present invention relates to a kind of multi-user's home energy source shared system based on energy cloud, the system packet
It includes：
Power grid；
Storage battery energy cloud, including multiple cell batteries；
Agent side, for investing, maintenance and management storage battery energy cloud, the agent side be equipped with information receiving module,
Combined storage battery module and Charging Module；
User terminal, including information sending module, payment module and energy-storage module are used for power grid purchase electric energy, or according to
Demand sends to agent side and rents information, completes corresponding reimbursement of expense and obtain the accumulator that Combined storage battery module provides
Complete charge and discharge or energy storage after energy storing space, the rental information includes the batteries to store energy capacity, most in period certain time
Big charge power and maximum discharge power.
There are a gauge table between storage battery energy cloud and user terminal, the power for being mainly used for controlling transmitted in both directions does not surpass
Cross the electric flux of maximum power limitation and detection transmitted in both directions.
The scheduling flow of present system includes the following steps：
S1：User terminal i rents the batteries to store energy capacity C of certain time cycle T according to the needs of oneself to agent sideB,i、
Maximum charge powerAnd maximum discharge powerAnd the accumulator as the user terminal within period certain time
Energy storing space.Storage battery energy cloud is made of a large amount of cell batteries, and agent side is according to the capacity and work(of the rental of user terminal
Rate size carries out connection in series-parallel to cell batteries.Investment, management and the maintenance of storage battery energy cloud are completed by agent side.It stores
Energy content of battery cloud allows a plurality of clients to be added simultaneously.For user terminal, user terminal is according to the electricity consumption situation and peace of family
The power generation situation for filling regenerative resource rents corresponding batteries to store energy space.User terminal only needs the expense that payment is rented and fills
It compensates or punishes caused by discharge mode, so that it may to use the batteries to store energy space on storage battery energy cloud.Using storage
When battery energy storage space, entirely family's accumulator is similar to using process.In use, it needs to meet following constraint：
1) in charge and discharge process, there is a conservation of energy in storage battery energy cloud always：
In formula：E (h) is the electric energy from storage battery energy cloud that user terminal is stored in time h,WithRespectively
It is user terminal to the charge power and discharge power of storage battery energy cloud,WithRespectively charge efficiency and discharging efficiency,
Δ h is the duration of each period, EiniFor the initial storage electric energy of user terminal.
2) power constraint：
In formula：WithThe respectively maximum charge power and maximum discharge power of storage battery energy cloud, in order to
Ensure charge and discharge mutual exclusion, sets the charging and discharging state judgment variable u of 0-1ESS(h), uESS(h) value indicates user terminal when being equal to 1
The accumulator group in corresponding batteries to store energy space is charging, and is equal to 0 and indicates the corresponding batteries to store energy space of the user terminal
Accumulator group discharging.
3) the electric energy constraint of storage battery energy cloud storage：
In formula, CB,iThe batteries to store energy capacity rented for user terminal.
The period of time T of rental is determined by user terminal.But in order to avoid the connection in series-parallel of frequent switching accumulator, rental
Minimum period is determined by agent side.
S2：It is family that user terminal selectively can buy electric energy in the electricity price lower period by power grid or agent side
Electrical appliance is energized or is stored in the batteries to store energy space of oneself rental, is rented from oneself in the electricity price higher period
It is that domestic electric appliances energizes or sell electric energy to agent side that electric energy is released in batteries to store energy space；
Power grid is bi-directional power flow.User terminal and agent side can buy electric energy from power grid, can also go out sale of electricity
Power grid can be given.But the electric energy for being sold to power grid needs to meet the requirements such as the frequency of grid power, phase and voltage class.In order to
The stable operation of electric system is improved, power grid encourages user terminal electricity consumption to be transferred to the low ebb phase.Therefore, power price is on-fixed
, the price of usual peak times of power consumption is higher than the low power consumption phase.
S3：Extra regenerative resource selectively can be stored in accumulator or be sold to agent side by user terminal；Add
Entering storage battery energy cloud does not require user terminal that must install renewable energy system.The user terminal for being fitted without regenerative resource can
To reduce the cost of household electricity by step S2.In order to reduce the investment of user terminal grid-connection device, user terminal can will be extra
Regenerative resource be sold to agent side, be uniformly processed by agent side and be sold to other users end or be sold to power grid.
S4：Agent side makes centainly the charge and discharge system of storage battery energy cloud in certain time cycle T according to user terminal
Reward or punishment.
The service life of accumulator is related with the mode of charge and discharge, and in order to extend the service life of accumulator, agent side is logical
Cross the mode that the charge and discharge system of user terminal is rewarded or punished and encourages user terminal specification charge and discharge.Battery discharging at
This is related with current state-of-charge SOC, and SOC is smaller, and electric discharge is more, is lost caused by accumulator bigger.Handling capacity method
It is a kind of simple and practicable life-span prediction method that is different according to each depth of discharge of accumulator and proposing.
Obtain corresponding to the equivalent handling capacity E of accumulator group after consideration life of storage battery loss weight in a cycle Tloss,H,
As following formula indicates：
In formula, function f () be with the relevant battery loss weight of corresponding storage battery charge state, given by agent side.
Therefore, rewarding and punishing expense C of the agent side to user terminalbatFor：
In formula, EB,lifeAnd CinstallThe handling capacity that respectively user terminal is rented in the entire lifetime of accumulator expresses energy storage
The cost of investment of system lifetim and corresponding accumulator；ω is rewarding and punishing coefficient of the agent side to user terminal；CmBe agent side to use
The depreciation threshold at family end.
In certain service life T, user terminal needs the expense C paid to agent side in totaluFor：
Cu=Cbat+Crent+Cchange
In formula, CrentThe expense of memory space is rented to agent side for user terminal；CchangeFor user terminal and agent side energy
The net charge of exchange.
By in family's energy-storage system of accumulator unification to storage battery energy cloud, user terminal can be rented the present invention as needed
The accumulator of respective volume, investment, maintenance, the management of storage battery energy cloud are all handled by agent side.Storage battery energy cloud is added
User terminal the extra electric energy of accumulators store can be sold to agent side, whole process avoids user terminal by extra electricity
The converter that power grid needs high requirement can be sold to.The present invention have the characteristics that it is at low cost, easy to operate, book on demand, can
It effectively avoids the problem that traditional-family's energy-storage system of accumulator exists, contributes to the hair for promoting intelligent grid and energy internet
Exhibition.
