Power generation là gì

According khổng lồ the twentieth century mã sản phẩm of energy distribution, large power plants fuelled by coal, hydro or gas, generated electricity that was distributed via a centralised grid.Quý khách hàng đang xem: Power nguồn generation là gì


What is distributed energy resources?

Now the picture has changed. Advancing giải pháp công nghệ has diversified the grid, adding new sources of energy generation & two-way power flows. Utility-scale wind & solar farms are supplying an increasing proportion of our power. Many Australian households generate their own electriđô thị via rooftop solar photovoltaic (PV) panels, which can then be stored using trang chính battery systems. Dem& response & smart meters are changing the way we consume electrithành phố, allowing users to lớn reduce consumption during peak periods to lớn help balance the grid.

Reliability has emerged as a major concern as the grid struggles lớn guarantee supply khổng lồ meet increasing demand, particularly during peak periods when expensive backup generation is required lớn keep the lights on.

Enter distributed energy resources, known as DER: small-scale units of local generation connected khổng lồ the grid at distribution màn chơi. Read more about it here.

The arrival of DER – a source of decentralised, community-generated energy – & its two-way flow of power is transforming the grid.

DERs can include behind-the-meter renewable & non-renewable generation, energy storage, inverters (electronic devices that change DC, or direct current, to lớn AC, or alternating current), electric vehicles & other controlled loads (separately metered appliances like hot water systems). DER also comprises new technology lượt thích smart meters and data services.

Common examples of DERs include rooftop solar PV units, natural gas turbines, microturbines, wind turbines, biomass generators, fuel cells, tri-generation units, battery storage, electric vehicles (EV) & EV chargers, & demvà response applications. These separate elements work together to lớn form distributed generation.

DER penetration is growing every year. The Electrithành phố Network Transformation Roadmaps (ENTR), a joint publication by Energy Networks nước Australia & the CSIRO, projected that over 40 per cent of energy customers will use DER by 2027. By 2050, that figure will grow to lớn more than 60 per cent.

The benefits DER brings lớn the grid

Affordability is one. Customers with access to DER assets can expect lớn pay less for electricity as they sell power back to the grid or are compensated for allowing their storage systems lớn help stabilise the grid, especially during peak periods.

Reduced network costs could also lead khổng lồ a fall in the overall cost of energy. One study found that investment in DER could reduce network expansion costs by nearly 60 per cent by 2050.

Reliability is another benefit. In areas where there is a high reliance on variable energy resources (VER) like wind và solar, DER can be deployed lớn help balance the grid and improve sầu its reliability, either reducing dem& or providing energy to lớn help smooth out intermittent supply.

A limiting factor is hosting capathành phố, or the amount of DER which can be connected to lớn a distribution network & operated within its technical limits. DERs can be incorporated inlớn the grid where no threats to safety, reliability or other operational features exist and no infrastructure upgrades are required. In many cases, however, grid modernisation is necessary to lớn safely integrate DERs inlớn the network.


California offers a useful case study in DER development. The state is a leading solar producer: rooftop solar penetration is more than 7 percent, và in năm ngoái, 10 percent of California’s energy came from a combination of solar thermal, utility-scale PV and rooftop PV. By 2030, 50 percent of the state’s power will be supplied by VER (wind và solar).

What we are doing

phonghopamway.com.vn is allocating more than $12 million in funding to optimise investment, improve sầu system performance & reduce technical, market, and regulatory barriers to increased uptake of DER in Australia.

The funding will be invested in network hosting capacity công nghệ & demonstration projects lớn develop new ways to underst& và manage the impacts of high DER penetration in different parts of the distribution network. This will allow networks to lớn connect more DER (such as rooftop solar PV panels) cheaper and faster while reducing costs và operating within the technical limits of the power system. Read about theDER projects we have funded.

Another slice of funding will be allocated khổng lồ new studies or models that contribute lớn increasing the value, capađô thị or efficiency of DER, or reducing costs or risks associated with its development và application.

These studies will help networks, retailers, phonghopamway.com.vnernment and system operators understand more about the technical and commercial challenges of managing a grid with a high penetration of DER. This could include identifying new ways of managing energy flows, better understanding how consumer behaviour might influence DER take-up or developing local or time-of-day incentives lớn encourage the use of DER.
