Fig. 2 is that expression is with the figure of solar cell as an example of the decentralized power s system of energy source.In addition, as decentralized power s, also can use the generator of the renewable energy resources beyond the solar cell.In Fig. 2; In demand user 1 (101); The decentralized power s system possesses solar panel 1011 and the power converter unit 1012 that is built-in with inverter (inverter circuit), and this inverter (inverter circuit) is transformed to alternating current to the direct current from these solar panel 1011 outputs.From industrial electric power system 204 via transformer station 212, and then via the circuit breaker 206, pole type transformer 108 and the circuit breaker 205 that cut off industrial electric power system 204 based on frequency change or change in voltage, to these power converter unit 1012 supply capabilities.Comprise circuit breaker 205 that breaks off decentralized electric power and the individual operation detecting unit 207 that makes circuit breaker 205 off-the-lines.
Based on the output voltage and the output current of solar panel 1011, the generated output of computing solar panel 1011.
Through control power converter unit 1012, across certain time interval the output voltage of solar panel 1011 is changed intermittently, the power of exploring output reaches maximum magnitude of voltage.Be provided with electricity accumulating unit 1013, discharge and recharge by 1014 controls of power converter unit.And pole type transformer 108 between be provided with fair tide electrical measurement unit 1017 and opposite tide electrical measurement unit 1018.Display unit 211 is when energy output is unusual, show when discharging and recharging when unusual etc.
In Fig. 1, thick line is represented electric power system, and fine rule is represented information system.Demand user 1～3 is connected with electric power data relay station 104 through communication network 106, and electric power data relay station 104 gathers center 105 through communication network 107 and electric power data and is connected.In addition, become from pole type transformer 108, and give the structure of system side the dump power opposite tide of solar panel 1011 through 109 pairs of each demand user supply capabilities of industrial electric power system.
Demand user 1 (101) possesses solar panel 1011 as generator unit; To be transformed to the alternating current of industrial frequency from the direct current of solar panel 1011 outputs through power converter unit 1012; Supply oneself load 1010 to use, at this, except solar panel 1011; Solar panel can also be set constitute a plurality of solar panels; Also other wind-driven generator can be set together, they are referred to as the generator based on regenerative resource, their energy output is called renewable electric weight.In this case, the result who amounts to energy output separately and get is regarded as the energy output of following explanation.
In addition, measure the output electric weight of power converter unit 1012 through solar power generation electrical measurement unit 1015.
Electricity accumulating unit 1013 can discharge and recharge direct current.When power converter unit 1014 is charged state at electricity accumulating unit; Input is from power converter unit 1012 or the alternating current supplied with of industrial electric power system (perhaps abbreviating system as) 109; Offer electricity accumulating unit 1013 after being transformed to direct current; When electricity accumulating unit 1013 is discharge condition, offer oneself load 1010 after will being transformed to alternating current from the direct current that electricity accumulating unit 1013 is supplied with, perhaps offer industrial electric power system 109 as opposite tide.
The dump power that oneself load 1010 can't consume in the electric power of solar panel head tide flows to industrial electro power system 109; Perhaps offer electricity accumulating unit 1013 via power converter unit 1014, its electric weight is measured through electricity accumulating unit charge/discharge electricity amount measuring unit 1016 and opposite tide electrical measurement unit 1018 respectively.
If can't keep oneself load 1010 through the electric power of solar panel, during power shortage, accept the supply of electric power from industrial electric power system 109, its electric weight is measured through fair tide electrical measurement unit 1017.
Electric quantity data transmitting element 1019 sends to electric power data relay station 104 to each electric weight that records respectively through solar power generation electrical measurement unit 1015, electricity accumulating unit charge/discharge electricity amount measuring unit 1016, fair tide electrical measurement unit 1017, opposite tide electrical measurement unit 1018 via communication network 106.
In addition, demand user 2 (102), demand user 3 (103) also are the structures identical with demand user 1 (101).
In electric power data relay station (perhaps abbreviating server as) 104; Through electric quantity data receiving element 1041 receive with pole type transformer 108 under the demand user's that is connected of electric power system above-mentioned electric quantity data, each demand user's of preservation above-mentioned electric weight in DB1042 such as electric quantity data.
In electric quantity data transmitting element 1019; With measure said opposite tide electric weight during, the state information that is arranged on equipment (being designated hereinafter simply as " equipment ") such as solar panel 1011 in the demand user 101, power converter unit 1012, electricity accumulating unit 1013, power converter unit 1014, oneself load 1010 (following abbreviate these state informations as " state information ") associates record with consumes power and opposite tide electric weight, and sends to electric power data relay station 104.
At this, can comprise solar panel 1011 as decentralized power s, with consumes power and opposite tide electric weight explicitly recording and sending can comprise the generating electric weight of this decentralized power s (can be more than 1) in the data of electric power data relay station 104.
Certainly, in the data of this transmission, comprise the charge capacity and the discharge electricity amount of at least more than one storage battery, and then comprise the information about having or not the enforcement charging and having or not the enforcement discharge of at least more than one storage battery.
Particularly under the situation of decentralized power s and storage battery coexistence, the equipment that is arranged in the demand user 1 (101) comprises at least more than one decentralized power s and an above storage battery, sends to electric power data relay station 104 to such information.
Better situation is, handle in order only when opposite tide takes place, to implement, the state information record measure the opposite tide electric weight during information, send to electric power data relay station 104.Perhaps, can't obtain measure opposite tide during the situation of state information of equipment under, can the opposite tide electric weight not sent to electric power data relay station 104 yet.In addition, can't obtain measure opposite tide during the situation of state information of said equipment under, also can the opposite tide magnitude of current be made as 0 and send to electric power data relay station 104.
Fig. 3 (a) is illustrated in the table of the data of preserving among the DB1042 such as electric quantity data.Receive from demand user 1 (101), demand user 2 (102), demand user's 3 (103) demand IDs that send, that be used to discern each demand user, fair tide electric weight, opposite tide electric weight, solar power generation electric weight, accumulator cell charging and discharging electric weight and savings preservation via receiving elements such as electric quantity data 1041.In the table shown in Fig. 3 (a), represented, had 3 required users, put aside the data that measure in October, 2009 and in November, 2009 by the example of putting aside electric weight every month.
In adjustment electric weight computing unit 1043,, calculate adjustment opposite tide electric weight through predetermined algorithm with reference to the savings data of DB1042 such as electric quantity data.This result of calculation is stored as DB1042 such as electric quantity datas shown in Fig. 3 (b).Using adjustment electric weight transmitting element 1044 will adjust the opposite tide electric weight via communication network 107 sends to and is arranged on electric power data and gathers and gather server 1051 in the center 105.According to the electric weight that in gathering server 1051, gathers, calculate the electricity charge in the future and each demand user is asked this electricity charge.
Fig. 4 representes the example by the calculation procedure of the adjustment opposite tide electric weight of adjustment electric weight computing unit 1043 execution.
When calculate certain demand user certain during adjustment opposite tide electric weight the time, judge whether accumulator cell charging and discharging electric weight during this period is on the occasion of (the charge ratio discharge is many).At this, in Fig. 3 (a), when storage battery 1013 chargings,, when storage battery 1013 discharges, be negative such define symbol for just.For example at the demand ID 001 of Fig. 3 (b), measure under the situation of time on date 2009/10, the accumulator cell charging and discharging electric weight be-150kwh, therefore is to discharge, and becomes " being (YES) " (step 4001).
If the accumulator cell charging and discharging amount be on the occasion of, then in the opposite tide electric weight, comprise the battery discharging electric weight, therefore will from the opposite tide electric weight, deduct the battery discharging electric weight and value be made as and adjust the opposite tide electric weight.At this, in Fig. 3 (a), represent discharge with negative sign, therefore as computing, become " opposite tide electric weight "+" accumulator cell charging and discharging electric weight (negative value) ", that is, adjustment opposite tide electric weight is made as the value that on the opposite tide electric weight, adds battery discharging electric weight gained.For example at the demand ID 001 of Fig. 3 (a), measure under the situation of time on date 2009/10, adjust the opposite tide electric weight and be set to 200+ (150)=50 (step 4002).
If the accumulator cell charging and discharging amount be not on the occasion of, then in the opposite tide electric weight, do not comprise the battery discharging electric weight, therefore, adjust the opposite tide electric weight and be set to opposite tide electric weight (step 4003).
Then, judge whether the solar power generation electric weight lacks than adjustment opposite tide electric weight.This be because, for example is connected with demand user 1 (101) when electric automobile, to demand user 1 (101) supply capability, perhaps during the interim or inflow of the generation power of fuel cell, produce opposite tide electric power from electric automobile above the solar power generation electric weight with inducting.For example at the demand ID 001 of Fig. 3 (a), measure under the situation of time on date 2009/10,50kwh is littler than solar power generation electric weight 100kwh for adjustment opposite tide electric weight, therefore thinks not to be above-mentioned state, is judged to be " not (NO) " (step 4004).
If the solar power generation electric weight then will be adjusted the opposite tide electric weight and be made as the solar power generation electric weight less than adjustment opposite tide electric weight.For example at the demand ID 001 of Fig. 3 (a), measure under the situation of time on date 2009/10, be set to resulting adjustment opposite tide electric weight 50kwh.This operation result is stored in as Fig. 3 (b) among the DB1042 such as electric quantity data (step 4005).
As another example, explanation demand ID 003, the situation of measurement time on date 2009/11 in Fig. 3 (a).In step 4001, the accumulator cell charging and discharging electric weight is 100kwh, for just, representes charging, therefore advances to step 4003, as adjustment opposite tide electric weight opposite tide electric weight 350kwh is set.
In step 4004,350kwh is bigger than solar power generation electric weight 300kwh for adjustment opposite tide electric weight, and conditional becomes " being (YES) ", therefore advances to step 4005.
In step 4005, will adjust the opposite tide electric weight and be made as solar power generation electric weight 300kwh.This value is stored among the DB1042 such as electric quantity data as the data shown in Fig. 3 (b).
Through calculating adjustment opposite tide electric weight like this, can calculate the electric weight that produces through solar power generation in the opposite tide electric power.
Through adjustment opposite tide electric weight like this, and should adjust opposite tide electric power and send to electric power data and gather the center, can buy the generation power of solar energy with predetermined buying rate.
In addition, in this execution mode, in the electric power data relay station, calculate adjustment opposite tide electric power, but also can gather the calculating that central side is implemented adjustment sale of electricity electric power at electric power data.At this moment, demand sends to electric power data to each electric weight that sends from the demand user and gathers central side.
In addition, in this execution mode, communication network 106 becomes the various network structure with communication network 107, but also can constitute through common communication network.
In addition, in this execution mode, in the electric power data relay station, calculated adjustment opposite tide electric power, but also can be in demand with indoor enforcement computing.
In addition, in this execution mode, in the both sides of decentralized power s and storage battery, be provided with voltameter, but also can under the state that voltameter only is set in decentralized power s, use.In this case, the generating electric weight of the decentralized power s of interim savings also is regarded as the energy output of decentralized power s.
In addition, the charging and discharging of accumulator voltameter can be only to judge the transducer that has or not enforcement to discharge and recharge.Opposite tide when in this case, the discharge of storage battery being arranged during measuring all is regarded as the discharged power of storage battery.
In addition; In this execution mode; All the time generating electric weight and the charging and discharging of accumulator electric weight with decentralized power s sends to the electric power data relay station with fair tide electric weight and opposite tide electric weight; But, also can be only when measuring the opposite tide electric weight, send the generating electric weight and the charging and discharging of accumulator electric weight of decentralized power s.In this case, can cut down the data volume of being sent.
In addition, when the generating electric weight that can't obtain decentralized power s for a certain reason and charging and discharging of accumulator electric weight, can the opposite tide electric weight not sent to relay station, perhaps the opposite tide electric weight is made as 0 and sends to relay station.Can prevent demand user's devious conduct thus.
