“…To reflect the SDGS performance in the individual subsystem, the performance score of indices belonging to the subsystem are summed up [53]. In the following section, the performance of each subsystem is compared to analyze the impact that is either beneficial or detrimental to each subsystem under five different scenarios.…”

Greater contradiction and conflict among urban green space, the development of social economy and the environment have occurred in Beijing. However, few studies have been conducted that consider the three subsystems as a whole. In this study, we defined sustainable development of green space (SDGS) as the coordinated development of the urban green system, social economy, and environment. Based on the datasets from 2000 to 2015, we forecast the SDGS in Beijing under multiple scenarios based on real-world policies using a system dynamics model. We found that the historical SDGS value increased to its highest level in 2012, but declined slightly by 2015. Second, the forecasted SDGS values declined over time in all scenarios, but the decline was greater in scenarios placing a high priority on economic development. In these scenarios, the performance of the indices only improved in certain subsystems. The simulation shows the implementation of the four policies proposed by the government failed to improve the overall level of SDGS in Beijing. This study could provide support for decision-making designed to improve the overall condition of urban green space in Beijing through integrated forecast and scenario simulation.

“…The Cp versus TSR graphs for the considered wind turbine configurations are tabulated in Figures 10 and 11. The coefficient of power, Cp is defined as 2P/(ρAV 3 ), where ρ is the air density and A is the frontal swept area of the turbine. The power generated by the turbine, P is measured by a controller which consists of a rectifier and resistive dump load.…”

“…According to the Organization of the Petroleum Exporting Countries (OPEC), this declining trend is likely to continue throughout 2015 [2]. At the moment, energy security is not only evaluated in economic perspective, but becomes more complex as it covers emerging global challenges, such as energy resource depletion, climate change, and geopolitical tension [3,4]. The limited capacity of the world to cope with the pollution caused by fossil fuels is one of the major considerations that has forced the world to seek alternative energy systems [5].…”

Design and Experimental Analysis of an Exhaust Air Energy Recovery Wind Turbine Generator

A vertical axis wind turbine (VAWT) was positioned at the discharge outlet of a cooling tower electricity generator. To avoid a negative impact on the performance of the cooling tower and to optimize the turbine performance, the determination of the VAWT position in the discharge wind stream was conducted by experiment. The preferable VAWT position is where the higher wind velocity matches the positive torque area of the turbine rotation. With the proper matching among the VAWT configurations (blade number, airfoil type, operating tip-speed-ratio, etc.) and exhaust air profile, the turbine system was not only able to recover the wasted kinetic energy, it also reduced the fan motor power consumption by 4.5% and increased the cooling tower intake air flow-rate by 11%. The VAWT had a free running rotational speed of 479 rpm, power coefficient of 10.6%, and tip-speed-ratio of 1.88. The double multiple stream tube theory was used to explain the VAWT behavior in the non-uniform wind stream. For the actual size of a cooling tower with a 2.4 m outlet diameter and powered by a 7.5 kW fan motor, it was estimated that a system with two VAWTs (side-by-side) can generate 1 kW of power which is equivalent to 13% of energy recovery.

“…With regard to the above, Kiriyama and Kajikawa [46] or Umbach [47] present a multilayered analysis of energy security research and the energy supply process as well as draw implications for global energy security. Moreover, there are various methodologies of energy security [48,49] as well as a plethora of methods, indicators, and measures often used in the research literature [50][51][52][53][54][55][56][57]. Smart grids or nuclear energy security are of a special interest [58,59].…”

Assessment of the Territorial Energy Security in the Context of Energy Systems Integration

et al. 2018

Our paper tackles the timely and highly-debated issue of assessment of the level of energy security for Russia’s territorial entities. Our analysis is carried out from the perspective of economic and management threats to reliable power supply for consumers caused by the process of integration of energy systems and the expansion of market regulation mechanisms. In particular, we focus on the creation and integration of energy systems using a case study of the remote territorial entity represented by Russia’s Far Eastern region that present a topic of special interest with respect to the subject and the scope of this research. We define and build the methods that might be used for determining the economically justified level of energy security under the market economy conditions based on ensuring a balance of interests between territorial government bodies and territorial generating companies in the process of forming a strategy for the development of a territorial energy system. Our results clearly demonstrate that current electricity tariffs and prices for the end consumers at the remote territorial entities, such as the Russian Far Eastern region, pose a threat to energy security since they are underestimated due to social and political concerns and often lead to unprofitable power generation. We argue that political consideration aside, energy systems creation and integration should be made viable and sustainable not only in Russia, but also in other countries. Our outcomes show that a more reasonable energy tariff policy might be appropriate when relevant stakeholders and policy-makers attempt to create conditions for the advanced development of remote industrial areas.
