home battery system Renewable energy investment leading to reduced reliance on centralised larger power generators

Australia's power system will become the most decentralized system in the world, because the steady growth of households and enterprises investing in renewable energy options has led to an increase in the use of distributed power generation, reliance on centralized power generation reduces large generators.Associate Professor Evan Franklin said:xa0Currently there are about 50,000 batteries in Australian homes, which were barely available two or three years ago."In fact, Australia is already one of the highest proportion of households in the world with solar photovoltaic [PV]xa0"On the roof, even Tasi already has about solar photovoltaic homes on the roof," said Associate Professor Franklin .
"Therexa0As the PV system becomes more affordable, its usage has been steadily increasing.It is predicted that in the next 15 years or so, one in every five households will have a battery installed."As we get more power from rooftop solar, wind and distributed photovoltaic power generation, the entire power system is changing, which means we are less and less dependent on coalPower plants and hydro generators that operate and help balance the system.
Associate Professor Franklin said there are many advantages to the decentralized energy system."The growth of distributed energy is primarily driven by consumers themselves, because in most cases, generating electricity on their own roofs with solar panels is cheaper than buying from power retailers, "said Associate Professor Franklin."It also provides them with more certainty and cushion against rising electricity prices.
"It allows consumers to gain a certain degree of autonomy and control over their energy use, and in some cases, it can also provide them with a certain degree of power outage security."Energy is generated close to where it is used, so it can reduce losses and the use of power networks."For the network itself, it can help manage the growth of network load, thereby minimizing the expensive investment in new infrastructure that is basically unnecessary.
Associate Professor Franklin is the lead researcher for $1.8 million study the potential of household battery systems to balance power supply.Australian researchers will work with industry and international partners to develop the functions of devices such as household battery systems to mimic the role of large generators in helping balance power supply.
"As we growxa0We operate fewer traditional large generators.These large generators currently play a key role in balancing the power system for the second timeby-The second basis, so we need to find a way to replace or even improve this function, "said Associate Professor Franklin.Associate Professor Franklin said the challenge for home batteries is that it is more complex to coordinate thousands of generators and energy storage devices than to coordinate a handful of large power stations.
"The flexibility of the new distributed technology can translate into advantages and be used to solve some complex problems," said Associate Professor Franklin .".Andrew Fraser, head of the TasNetworks network innovation team, said the company believes Australia's growing distributed energy team will play an important role in helping the system balance."Without smart coordination, make sure they are running within the physical grid at all times, that will not happen," Mr Fraser said .
