How solar power parity era, photovoltaic power generation from 'adapt to electricity' to 'support the electricity'?

Due to the effect of resources and environmental factors such as climate, photovoltaic power station often is located in the area of power grid structure is weak. With the increase of new energy access, SCR coming down. For example, when the dc transmission failure atresia, photovoltaic power station near the HVDC fault point and node voltage transient peak will appear, photovoltaic power station must have good adaptability to the power grid transient phenomenon. Studies have shown that in the weak power grid environment, traditional solutions are prone to poor quality of electrical energy, photovoltaic engineering subcontract price photovoltaic power output is not stable, even to take off the net.

huawei intelligent inverter devices for stronger control ability, support the SCR limit 1. 5, the absolute leading position in the industry. Let the parity era, photovoltaic engineering subcontract price more access to the new energy. Huawei AI BOOST smart grid algorithm, supporting high pv parity Internet era scene, help to solve the large-scale, high proportion of new energy grid stable operation of world-class puzzle. Huawei will communications industry accumulated years of experience in software algorithm, weak power grid operation introduction of photovoltaic industry, Pan Jingong generating agent has established the precision of different types of glass grid scenario, plant design, engineering management platform solar building case grid working point of mathematical model, the optimal grid control algorithm, using big data training and under all kinds of bad power grid waveform can ensure continue grid power inverter, not to take off the net, and the power quality meet or exceed standards. Guide & photovoltaic power generation from the other To adapt to the power grid & throughout; Go & other; Support power grid & throughout; 。 After using huawei AI BOOST intelligent grid algorithm, one-time success grid, power quality significantly better than with regional power station. The Indian state of a 100 mw intelligent photovoltaic power station, located in the remote mountainous area, through multistage booster grid, biomass power project belongs to a typical weak power grid scenario. The project adopt huawei intelligent photovoltaic (pv), intelligent inverter in the situation of low short circuit capacity and stable operation. Photovoltaic power generation is the most rapid development, and the most promising one of the renewable energy industry. When the photovoltaic power station and distal trunk and branch power grid impedance is small, the equivalence between the grid photovoltaic power station in the power rating runtime power station and node voltage amplitude and phase are close to Yu Yuanduan backbone grid, then the stable operation of the photovoltaic power station; When the photovoltaic power station and distal trunk and branch power grid impedance is bigger, the equivalence between the power grid will bring voltage instability, harmonic resonance frequency instability, subsynchronous oscillation and a variety of problems, such as serious will cause the photovoltaic power station network devices and power grid failure, and even harm the local power grid security and stability of luck in the new AI BOOST intelligence photovoltaic (pv) 6. 0 scheme, huawei in the industry for the first time since the introduction of impedance remodeling AI learning algorithm, dynamic damping adaptation algorithm fusion, solar portal, smart series compensated adaptive algorithm, active harmonic suppression algorithm and other leading parallel algorithm, dynamically adjusted by AI self-learning electric character of the power station to match the power grid, solar panels, to keep power grid stability, photovoltaic (pv) grid, not to take off the net. The power station are all made of huawei's intelligent photovoltaic solutions for poverty alleviation, the grid fault eliminating all photovoltaic power station and stable work. With ever increasing proportion in power system, high reliable photovoltaic grid problems highlighted increasingly, has seriously restricted the industry healthy and sustainable development, caused the wide concern from all walks of life. At the same time, in remote areas, weak power grid, long distance transmission, solar panels, solar energy mix water valve how much high voltage direct current transmission and so on various factors together, also can bring challenges to the friendly grid photovoltaic power station. A 26 in ningxia. 68 MWP pv poverty alleviation village-level power station, located in the remote mountainous areas, involving 89 funding a 12 towns, rural weak power grid voltage, the frequency is not stable, more power stations for poverty alleviation and connected to the electricity grid is easy to cause resonance and abnormal voltage. Inner Mongolia a 100 MW photovoltaic power station, intelligent distance more than 80 km, 110 kv and branch short circuit capacity ratio of 2, belongs to the typical weak power grid scenario. Short circuit capacity ratio ( 可控硅) Is an important index of power grid and branch strength, the smaller the value, the grid is weak, how much solar energy mix water valve grid stability more difficult; Space truss structure is fragile, solar panels, short circuit capacity is small, weak power grid at the end of the biomass power project tends to access the situation.
