According to lớn the twentieth century Model of energy distribution, large power plants fuelled by coal, hydro or gas, generated electricity that was distributed via a centralised grid.Quý khách hàng sẽ xem: Power nguồn generation là gì


What is distributed energy resources?

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

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

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

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

DERs can include behind-the-meter renewable and non-renewable generation, energy storage, inverters (electronic devices that change DC, or direct current, to AC, or alternating current), electric vehicles và other controlled loads (separately metered appliances like hot water systems). DER also comprises new công nghệ like smart meters & 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) and EV chargers, & demvà response applications. These separate elements work together khổng lồ size distributed generation.

DER penetration is growing every year. The Electricity Network Transformation Roadbản đồ (ENTR), a joint publication by Energy Networks Australia and 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 to lớn the grid

Affordability is one. Customers with access khổng lồ DER assets can expect to pay less for electrithành phố as they sell power back khổng lồ the grid or are compensated for allowing their storage systems to 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 khổng lồ help balance the grid and improve sầu its reliability, either reducing dem& or providing energy khổng lồ 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 và operated within its technical limits. DERs can be incorporated into the grid where no threats khổng lồ safety, reliability or other operational features exist & 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, and in năm ngoái, 10 percent of California’s energy came from a combination of solar thermal, utility-scale PV & rooftop PV. By 2030, 50 percent of the state’s power will be supplied by VER (wind và solar).

What we are doing is allocating more than $12 million in funding to optimise investment, improve sầu system performance và reduce technical, market, & regulatory barriers khổng lồ increased uptake of DER in nước Australia.

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

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

These studies will help networks, retailers, chrissiemanby.comernment và system operators understand more about the technical và 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.
