Due to excessive resource consumption and pressing environmental issues of the sewage treatment industry, there is extensive attention in China. Given the unique craft production process in the sewage treatment system, a series of integral emergy indicators have been used to evaluate the environmental sustainability based on infrastructure construction and operation stage emergy analysis. Taking a new typical sewage treatment plant as an example, this paper performed a case study. The results illustrate that (1) the infrastructure construction process emergy (approximate 92.6%) is more critical than sewage treatment process emergy; (2) nonrenewable resource is the primary factor for the emergy analysis, followed by energy (23.5%) and purchased supply (7%); (3) cement, steel, and gravel have dominant impacts on the nonrenewable resource emergy; (4) the emergy sustainability index is 0.001101, which displays weak environmental sustainability; (5) the unit emergy value (UEV) of the new sewage treatment plant is 3.40 × 10 12 sej/m 3 ; (6) sensitivity analysis results of the hypothesis demonstrate that nonrenewable resources have significant fluctuations (6.903%) while, for the indicators, emergy sustainability index (ESI) (4.8072%) has the most significant impact; and (7) wastewater is a major contributor. In light of comprehensive discussions, two positive measures are proposed in order to ameliorate the environmental sustainability.Water 2020, 12, 484 2 of 23 between the environment in the sewage treatment industry using biological perspective analysis [5][6][7][8], lifecycle assessment (LCA) perspective [9], ecology models perspective [10], energy and economy performances [11], sewage treatment and water supply efficiency [12], chemical and physical angles [13,14], construction in the wastewater treatment plants [15], integrating wastewater treatment and incineration plants for energy-efficient study [16], sampling strategy for the sewage sludge survey [17], soil and the treatment of sewage treatment plant [18], and systematic assessment framework [19].However, these studies have the following drawbacks: (1) for the isolated angles analysis, only one or some perspectives are chosen to demonstrate the interaction between environmental issues and the sewage treatment industry, resulting in a few unilateral conclusions; (2) ignorance of natural resources assessment leads to a negative impact on sustainability in the sewage treatment industry; (3) undifferentiated contribution degrees from different resource types could cause deviation inaccuracy to some extent; (4) there is a lack of a unified platform to evaluate sustainability in the sewage treatment industry, for example, an integrated method assessment should comprise resources, energy, labor, and others; and (5) some studies are unable to consider multiple pollutant emissions simultaneously, such as exhaust gas, wastewater, and solid waste. It will have a harmful effect on sustainability in the sewage treatment industry. In summary, the above studies cannot disp...

The need to incorporate renewable energy sources in the present grid due to energy demand and environmental issues has led the power industry to face new challenges and unexpected transformations. This new epitome to build a flexible power system with coordination of increasing intermittent renewable energy resources and delivering power efficiently with reliability demand new technologies. This work investigates the coupling of static synchronous compensator (STATCOM) with the most exclusive superconducting magnetic energy storage (SMES) device designed for the improved functioning of a grid network that is incorporated with a wind farm. The widespread integration of intermittent wind generators in the grid is disturbing its stability and reliability. The SMES is interlinked with the grid system via a power electronic interface and chopper for the energy exchange. This work suggests STATCOM as a power electronic interface and a three‐level chopper configuration with novel control scheme for enhancing the functioning of the test system. This integrated controller (STAT‐SMES) has been analyzed for grid‐connected doubly fed induction generator wind farm under different fault conditions and time durations. The results have been compared without any controller, with STATCOM only, and with the proposed STAT‐SMES controller using MATLAB. The simulation outcomes prove that coupled control scheme is effective and better in handling wind farm integration issues.

The Superconducting Magnetic Energy Storage (SMES) device is gaining significance in utility applications, as it can handle high power values with a fast rate of exchanging energy at high efficiency. The large-scale invasion of renewable energy systems into grid give rise to many integration issues. This SMES can handle these issues due to its various features. In this study the role of SMES in tackling stability issues due to presence of wind generation farms is investigated. The Doubly Fed Induction Generators (DFIG) based wind farms are most popular due to their distinctive advantages. Their intermittent output power and sensitivity to the grid disturbances gives rise to stability issues. These problems require innovative and advanced control strategies. Here coupling of SMES with Static Compensator (STATCOM) (STAT-SMES) has been suggested for boosting the transient stability of the hybrid large-scale DFIG and Synchronous Generator (SG) system. For investigation different faults and fast speed wind variation are considered. This coupled controller can compensate the real and reactive powers along with fast damping of oscillations under test conditions of entire system. The chopper link of SMES is controlled using Fuzzy based intelligent system and Proportional Integral (PI) controller. The connection of SMES to STATCOM shows better damping and improvement in all variables. The comparative study among Fuzzy based STAT-SMES, PI based STAT-SMES, only STATCOM, and without any controller is performed using MATLAB/Simulink. The simulation outcomes indicate that proposed Fuzzy based controller is better than other control systems in different test conditions.
