“…Low-carbon living could be based on technological solutions, such as energy efficient housing, heat pumps, home energy management systems (HEMS), and hybrid or electric vehicles combined with new energy solutions for homes. 76,77 These types of technological solutions are also likely to have positive spillover effects in addition to or instead of the negative rebound effects of consumption. 21 In light of our results, it seems that the new legislation regarding the efficiency of buildings is working quite well for new housing in outer and peri-urban areas.…”

Avoiding urban sprawl and increasing density are often considered as effective means to mitigate climate change through urban planning. However, there have been rapid technological changes in the fields of housing energy and private driving, and the development is continuing. In this study, we analyze the carbon footprints of the residents living in new housing in different urban forms in Finland. We compare the new housing to existing housing stock. In all areas, the emissions from housing energy were significantly lower in new buildings. However, in the inner urban areas the high level of consumption, mostly due to higher affluence, reverse the gains of energy efficient new housing. The smallest carbon footprints were found in newly built outer and peri-urban areas, also when income level differences were taken into account. Rather than strengthening the juxtaposition of urban and suburban areas, we suggest that it would be smarter to recognize the strengths and weaknesses of both modes of living and develop a more systemic strategy that would result in greater sustainability in both areas. Since such strategy does not exist yet, it should be researched and practically developed. It would be beneficial to focus on area specific mitigation measures.

“…Both active and reactive power of MS1 are unstable during the fault in both V and Q control, but more visible instability is observed under V control regime. Voltage and frequency instability is a major challenge of microgrid operation, as published in [30][31][32][33]. During the fault, the transformed stator voltages of MS1 is disrupted in the  , and  axes as the severity of the fault is higher than L-L faults that are not cross-country, as shown in Fig.…”

“…Both active and reactive power of MS1 are unstable during the fault in both V and Q control, but virulent and sustained instability is observed under V control regime. Voltage and frequency instability is a major challenge of microgrid operation, as published in [30][31][32]. The DFIG remained in generation mode under Q control while it changed to motoring mode under V control when exposed to 3-phase bolted short circuit.…”

This paper is presented in an attempt to validate the dynamic response of a microgrid to line-to-line short circuit. The microgrid components include two identical Wind Turbine Generators (WTGs) tied to a 100MVA, 13.8kV utility via a Point of Common Coupling (PCC). The utility-microgrid testbed is modeled in SIMPOWERSystems® using two Doubly-Fed Induction Generators (DFIGs) in the microgrid side. While in islanded operating mode, line-to-line short circuit fault is applied at 6.0s and withdrawn at 8.0s, obtaining a 50.0s dynamic response of the system for different fault locations, under voltage and reactive power control regimes of the wind turbine controller. For measurement purpose, the absolute value of the stator complex voltage is transformed to reference frame. Bidirectional power flow between the two feeders is established in the study. The study also confirms that the microgrid composed of DFIGs offer reactive power management capability, particularly by presenting superior performance when stressed under Q control regime than under V control regime. Finally, the response of the testbed to line-to-line short circuit has been validated and shown to be consistent with established short circuit theory.

“…Power dispatching problems [39] including ESS deals with communications of several different SG components, such as energy storage devices, DER and forecasting agents. PEVs are one of the most viable technologies for achieving the goals of energy saving and environmental protection before the breakthrough in battery technology and fuel cell technology [85], its penetration is expected to increase significantly in the next 20 years [24]. Bidirectional power flow between PEVs and the grid will become essential [86] and coordinating this new wave of plugand-play vehicles is a claiming burden.…”

“…Furthermore, additional components added or improved by consumers will be integrated to the SG, imposing new frontiers for MG control and management. For example, Plug-in Electric Vehicles (PEV) [24] are being integrated to the power grid (specially with the rise of smart charging parks, known as, SmartPark [25]), imposing new grid constraints, requirements and goals, settled by its users. Coordination and integration of DER in MG systems have been the focus of different researches and remain complex tasks [26].…”
