Factors Affecting Workability01:24

Factors Affecting Workability

68
The workability of concrete is a critical characteristic that influences the ease of mixing, handling, and finishing the concrete. It is affected by several factors including water content, aggregate properties, and admixtures like air entrainment. Water plays a fundamental role as it lubricates the concrete mix, facilitating easier movement and placement. However, the water requirement varies depending on the texture and shape of aggregates. Finer particles and angular, rough-textured...

Secondary Distribution01:25

Secondary Distribution

83
Secondary distribution systems provide electrical energy at the utilization voltage levels from distribution transformers to customer meters. Typical secondary voltages in the United States include 120/240 V for residential use, 208Y/120 V for residential and commercial use, and 480Y/277 V for industrial and high-rise commercial use.
In residential areas, 120/240 V single-phase, three-wire service is commonly used for lighting, outlets, and large appliances. Urban areas with high-density loads...

Power System Distribution01:25

Power System Distribution

229
Power system distribution involves delivering electrical energy from power plants to consumers through a network of transmission and distribution systems. The process begins at power plants, where energy from coal, gas, nuclear, water, and wind is converted into electrical energy. These plants use three-phase generators, typically rated between 50 to 1300 MVA, with terminal voltages ranging from a few kV to 20 kV, depending on the size and age of the units.
The transmission system is designed...

Electrical Power01:07

Electrical Power

3.0K
Electric power is the product of current and voltage, represented in units of joules per second, or watts. For example, cars often have one or more auxiliary power outlets with which you can charge a cell phone or other electronic devices. These outlets may be rated at 20 amps and 12 volts, so that the circuit can deliver a maximum power of 240 watts. Consider a 25 Watt bulb and a 60 Watt bulb. The conversion of electrical energy produces heat and light, while the kinetic energy lost by the...

Conservation of AC Power01:15

Conservation of AC Power

330
The principle of power preservation is applicable to both ac and dc circuits. This principle, when applied to AC power, asserts that the complex, real, and reactive powers produced by the source are equal to the total complex, real, and reactive powers absorbed by the loads. When two load impedances are connected in parallel to an ac source V, the complex power provided by the source can be calculated using the relation

Summary

Community microgrids can ensure power during blackouts. Residents support differentiated energy pricing and are willing to sell stored power, indicating social acceptance of energy-as-a-service models.

Area of Science:

  • Energy policy
  • Societal impact of energy infrastructure
  • Renewable energy systems

Background:

  • Extreme weather events frequently cause widespread power blackouts.
  • Localized energy resources, known as microgrids, offer a solution for maintaining critical electricity supply.
  • Community microgrids require effective energy rationing strategies during prolonged outages.

Purpose of the Study:

  • To survey US residents' preferences on rationing finite microgrid energy during blackouts.
  • To assess public acceptance of a differentiated service model for energy allocation.
  • To understand willingness-to-sell stored energy from personal backup devices to the microgrid.

Main Methods:

  • Survey of 1021 US residents regarding energy rationing preferences.
  • Analysis of responses concerning differentiated service and willingness-to-sell.
  • Identification of factors influencing perceptions of fairness in energy allocation.

Main Results:

  • Over 91.8% of respondents supported a differentiated service paradigm, allowing higher energy quotas for increased payment.
  • Respondents indicated a willingness-to-sell between 42-53% of their stored energy to the microgrid.
  • Factors influencing fairness perceptions were identified for both consumers and storage owners.

Conclusions:

  • A differentiated service model for energy rationing in community microgrids is highly supported by the public.
  • The concept of willingness-to-sell stored energy highlights a balance between self-preservation and economic incentives.
  • An energy-as-a-service model is deemed socially acceptable for community microgrids, offering valuable insights for policymakers and businesses.
