Change cross flow electric

Sun energy cell board output's straight flow electric pressure at white sky follow follow light shine strong degree from 400 volts violent violent wave move to 1000 volts. Store energy cell cluster's end electric pressure by string connect lock fix at 1200 volts to 1500 volts area exactly. Want take straight flow electric merge enter big electric net, store energy reverse change device (PCS) take every second 20000 times' frequency rate hold row open shut move make, take straight flow electric cut cut, heavy group and level smooth become standard rule's 480 volts or 800 volts three phase cross flow electric. Carbon chemical silicon (SiC) field effect answer tube take high frequency open shut pass process's physical energy lose consume drop low did 40%.

Full load run row time, absolute edge grid double pole shape crystal body tube (IGBT) model block's surface face temperature will at 5 minutes inside whirlwind rise to 85 Celsius degrees. Water cold system pass cross every minute 25 liters flow speed's cold back liquid, strong row take model block work temperature press system at 65 Celsius degrees inside.

One set 5 megawatts' mix join reverse change device every day full power turn move 10 hours, high reach 98.5%'s transform change effect rate rely natural have about 750 kilowatt hours' electric energy will transform change become waste hot. Cross straight flow transform change pass process will happen produce huge big amount high times answer wave, LC filter wave device profit use 800 micro henries' electric feel and 400 micro farads' electric hold enter row physical block cut, take output electric flow's total answer wave lose real rate (THD) dead dead press system at 1.5% to 2.5% exactly between.

New energy source high seep penetrate rate local area's electric net short circuit capacity compare (SCR) experience often fall break 3.0's physical border limit, present out extreme its weak weak's weak electric net special exact. Electric net block resist increase add 10 milli ohms, reverse change device's lock phase ring (PLL) count method lose go same step track follow mark purpose's probability rate will increase add 20%.

Electric net electric pressure happen produce light micro's 5% non-pair scale nature drop fall, negative sequence electric flow will at reverse change device inside part happen produce 120 hertz's low frequency power shake move. Hard piece work exact master pass cross pour enter block resist heavy shape count method, at 400 hertz to 1000 hertz's middle frequency section increase add empty fake block stop, take merge net answer shake peak's shake width strong row cut subtract 15 divide shells, protect barrier system at electric net block resist violent violent wave move time rely old protect keep merge net connect join state form.

Steady live frequency rate

North America electric net's cross flow electric physical pass deliver frequency rate must extreme its exact exact ground maintain keep at 60 hertz. Load sudden increase lead cause electric net frequency rate drop fall arrive 59.95 hertz time, phase amount measure measure single original (PMU) at 10 milli seconds inside catch catch arrive micro small's electric pressure phase angle lean shift. Store energy reverse change device inside set's empty fake same step send electric machine (VSG) count method blink time cut enter, ask ask setup device at short short 20 milli seconds inside from zero output state form burst send, towards electric net pour enter forehead fix capacity 10%'s real exact have work power.

Discharge electric power every second's climb slope speed rate by strict limit limit system at total install machine capacity's 10%. One machine install machine scale model for 10 megawatts' store energy electric station, from wait machine cut change arrive full load merge net discharge electric, must hold row long reach 10 seconds' level smooth climb slope curve line, prevent stop hundred megawatt level grade's blink state power reverse pour burn destroy area domain change electric station's 50 mega volt amperes main change pressure device. Frequency rate exceed tone amount by control system at forehead fix power's 0.5% inside, steady state mistake difference fan round shrink small arrive positive negative 0.02 hertz, every one time answer answer's tone exactly time strict limit limit system at 1 second inside.

Mistake open high peak

Light volt array row's straight flow side install machine amount pass often press follow reverse change device cross flow side capacity's 1.2 times to 1.3 times enter row exceed match. Exact noon time divide, one piece hold have 5 megawatts light volt face board and 4 megawatts reverse change device's electric station, will have 1 megawatt's peak value output because reach arrive reverse change device's physical transform change up limit and face look “cut peak” waste cost. Straight flow couple join store energy system pass cross most big power point track follow (MPPT) control device, take cut break's straight flow electric lead flow arrive cell cluster, charge electric transform change effect rate high reach 98.5%. Cross flow couple join plan exact need need first take straight flow reverse change for cross flow, again by store energy reverse change device transform change back straight flow store enter cell, two roads transform change work order will make become about 8% to 10%'s electric amount decline reduce.

California stand alone system run business merchant (CAISO) tube govern's electric power batch send market place, down noon 2 o'clock's present goods electric price pass often low arrive every megawatt hour 15 US dollars, even arrive out present negative electric price. Store energy electric station at this time take 750 kilowatts' constant fix power suck accept electric net pass surplus electric amount continuous keep charge electric 4 hours. Night up 7 o'clock to 9 o'clock's clean load peak value time section, present goods electric price whirlwind rise arrive every megawatt hour 180 US dollars above. Electric station take 1.5 megawatts' full carry power continuous keep discharge electric 2 hours, single time charge discharge electric cycle period wrap profit hit remove 85%'s system gather together go return effect rate (RTE) lose consume after, single day clean receive benefit rate lift rise about 45%. Every month capacity electric fee's divide share compare rate down drop did 30%, throw capital return report cycle period shrink short arrive 4.2 years.
