“…),and T i j t = v i,t v j ,t sin(𝜃 i,t − 𝜃 j ,t )are defined as in [20], where 𝜈 i,t , 𝜈 j ,t are the voltage magnitudes of buses i and j at time t, and 𝜃 i,t , 𝜃 j ,t are the phase shift angles of buses i and j at time t, respectively. The power flow through the distribution lines is expressed as a function of the previously defined auxiliary variables in (10) to (11), where variables u i j i,t , u i j j ,t are used to define the voltages at the sending and receiving ends of each line depending on its status, g i j , b i j ,and b i j sh are the conductance, susceptance, and shunt admittance of power line ij, respectively. The distribution line flow is limited to the maximum line capacity S i j in (12).…”

“…When the line is connected and operates normally, that is, 𝛼 i j,t = 1, u i j i,t , u i j j ,t are equal to 𝜈 i,t , 𝜈 j ,t ,respectively, with a maximum value expressed as a function of the maximum bus voltages at line ends i and j, v i , v j . If the line is disconnected, 𝛼 i j,t = 0 sets u i j i,t , u i j j ,t to be equal to zero, forcing R i j t , T i j t to zero (17), together with the power flow in (10) to (11). A conic relaxation is used in (17) to solve the problem as a SOC programming model, which converges to a unique solution due to the radial configuration of the distribution systems [21].…”

“…In the research community, efforts towards energy justice have mainly revolved around long‐term infrastructure investment and tariff design to tackle inequitable access to modern infrastructure upgrades and energy poverty. An assessment on the access to electric vehicle infrastructure in New York City is developed in [11], showing the need for policies to incorporate equity into the electric vehicle infrastructure expansion. A tariff design scheme is introduced in [12], which improves the operational savings in the system without hindering distributional equity.…”

The efficient, reliable, and resilient supply of electricity has become essential for social and economic well‐being of the modern society. However, more frequent occurrence of extreme weather events has exposed inequity in the planning and operation practices of power distribution systems, evidenced in higher vulnerability and longer power interruptions for some parts of the grid as compared to others. This paper proposes an equity‐aware power distribution system restoration model in an effort to ensure a more equitable yet resilient power distribution operation after outages. To this end, the proposed equity‐aware distribution system restoration model balances the efficiency of the restoration operation and the equitable allocation of distributed energy resources among affected customers after an outage, while prioritizing the critical infrastructure (e.g. hospitals). The results demonstrate the effectiveness of the proposed framework to ensure a more equitable restoration process as measured by the proposed fairness and restoration performance indices.

“…The development of electric-powered vehicle charging facilities in Japan has reached nearly 7,000 so far, which also promotes the rapid leap of this Japanese electric-powered vehicle technology. The United States [4] has the earliest start and strong foundation for electric-powered vehicle development. The construction of DC charging facilities for electric-powered vehicles in the United States ranks among the best, and its DC charging equipment covers almost the entire United States.…”

As a high-standard verdant method of transportation, electric-powered-vehicles have become the development hotspot of the automotive business in recent years. Large scale access to electric-powered vehicles can form a distributed energy storage system, which can improve the operational performance of power grid peak shaving and frequency modulation, and improve the comprehensive utilization efficiency of system energy. But at the same time, large-scale electric-powered vehicles connected to the DC distribution network will have a certain impact on its topology. Therefore, this paper studies the impact of the access location and number of electric-powered vehicles on the network topology and establishes a multi-dimensional evaluation system of the DC distribution network topology. The application of this result can play an evaluation and guidance role in the operation stability of the DC distribution network in the case of large-scale access to electric-powered vehicles.

“…Electric vehicles (EVs) are a solution, but attention has focused on the wealthy [5] and future technologies, [6][7][8][9][10][11][12][13] both of which won't immediately lessen climate change. Lower-income residents need and do not have equal access to EV charging [14]. A federally funded program installs public charging stations on interstate highways, [15] yet not all use the highway, basic charging requires waiting hours, and Tesla owners are the primary beneficiaries of fast charging.…”

With climate change and inequities, this study assessed the willingness of affordable-housing and middle-income residents to buy an electric vehicle (EV) if they had a charging station at their home, the likelihood of buying an EV in 2 years, ideal charger locations, and payment preferences for installation. The new Green Books revealed charger opportunities. Volunteers completed paper surveys in Brookline, MA, in an affordable housing complex (n = 37) and a middle-income neighborhood (n = 128) (Total n = 165). Brookline is unique because drivers cannot leave their cars curbside overnight, and local historic districts (LHDs) require aesthetic charger-installations. Descriptive statistics (yes + likely) revealed that affordable housing (70%) and middle-income (65%) respondents would lease or buy a secondhand EV if they had a charging station where they park their car at their home. Affordable housing (43%) and middle-income (38%) respondents were more neutral about buying an EV in the next 2 years. The preferred charger location was the side of the house (44%) or a post by the driveway (38%). Preferred cost-for-installation included government reimbursement (47%) and tax deduction (41%). Data analysis combined affordable housing and middle-income responses and showed no significant differences for gender, significant differences for individuals 76 years and older, and minor differences for income. To inform individuals in the pre-contemplation phase, Black-owned businesses in the new Green Books could seek government funding for off-road chargers. While EV technology will improve, land is limited, so chargers should not displace climate-responsive bicyclists in curbside protected bike lanes. Following this study, governments and academics could pilot full funding of home charger installations to involve affordable housing and middle-income residents in this climate change solution, study details of these adopters, and develop worldwide policies to lessen greenhouse gas emissions.
