Robust Scheduling Optimization Model for Combined Cooling, Heating and Power System in Industrial Parks

The multi energy complementary system is a new power energy technology Firstly, we studied renewable energy and load uncertainties of an operation optimization system, and established the industrial park energy system, which includes wind power, photovoltaic power, a combined cooling, heating and power system, and an energy storage tank. Secondly, given the renewable energy uncertainties of unit output and load, we introduced a robust multi-objective operation optimization method for industrial park energy supply systems while considering conservative system operation. Thirdly, we examined the synergetic and game relationship among multiple objectives. The particle swarm optimization algorithm is was used to optimize the system operation scheme, reduce the feasible domain, and improve the efficiency of the solution. Finally, the simulation results show that the operation optimization method effectively uses the demand response to optimize economic and environmental objectives and ensure the optimal operation efficiency of the system under multiple uncertainties.

Modeling impacts of industrial park activity on air quality of surrounding area for identifying isolation distance: A case of Tan Tao Industrial Park, Ho Chi Minh City, Viet Nam

Industrial factories have been addressed as the main contributor to the amount of air pollution in many urban areas around the world. The emissions of air pollutants from factories, combined with exhausted gases from automobile and domestic cooking activities, have placed enormous adverse effects on human health. Recently, air quality models, which usually figure out for industrial emission with representative indicators such as CO, NO2, SO2, and TSP, have triggered an application to identify a suitable isolation distance that could lessen affection on public health. Concerning to develop an air emission inventory for Tan Tao Industrial Park (IP) for three sources of points, line and area sources by using top-down and bottom-up approaches, this study aim to: (i) apply a system model of TAPM – AERMOD model to study the air pollution dispersion from the IP to the surrounding area, and (ii) identify a hygiene isolation distance for sensitive objects around industrial park, especially zones of community, based on their separating demand from contamination. Results show that the point sources are the dominant air emission sources of Tan Tao IP. Total emissions of Tan Tao IP in 2019 estimated at 413.15 tons of TSP/year, 280.9 tons of NO2/year, 621.99 tons of SO2/year, and 2720.21 tons of CO/year. Modeling results show that 1-hour maximum concentration of TSP, NO2, SO2, and CO in the simulation area is 581µg/m3, 4.069µg/m3, 5.478µg/m3, 40.695µg/m3, respectively, exceeding the standards. Especially, the pollution levels of NO2 were 20 times higher than the limit value, similar trends for SO2 (15 times higher). The hygiene isolation distance was suggested a widely ranged from 2910 meters in the North-West and in the rest directions of Ho Chi Minh City. Some sensitive objects such as residential areas, hospitals and kindergartens recently are inside the affected zone should be reckoned to have suitable solutions that keep their health safe. The method for calculation of hygiene isolation distances from industrial activities has a significant guiding not only for environmental safety action but also for public health protection.

The impact of petroleum contamination on the ecological conditions of the Dendrological park “Oleksandriya”

Within the territory of the Dendrological park Oleksandriya subsurface contamination with petroleum prod- ucts, the source of which is a former aircraft repair plant, has existed for a long time. The circumstances of the formation of ecological and hydrogeological situation on the territory of the dendrological park under the influence of petroleum con- tamination from the technogenic loaded area are considered in order to create the system of control of potentially negative impact on the environment and planning of remediation actions. The creation of the eco-industrial park Bila Tserkva will minimize the man-made impact on the state of the underground hydrosphere of the dendrological park.

Dynamic Test and Analysis of the Structure of the Stadium Stand in Suzhou Industrial Park

The test object is the grandstand of the Suzhou Industrial Park Stadium. First, the structure was tested for dynamic characteristics, including natural frequency, mode test, and damping test. Then, the structure was subjected to a human-induced vibration response test. Lastly, the finite-element modeling of the structure was carried out, and the simulated and measured values were compared. The test results of the dynamic characteristics of the structure are consistent with the calculated values, and the finite-element modeling of the structure was accurate and reasonable. The natural frequency of structural modal test areas 1 and 2 met the 3 Hz limit vibration specified by JGJ/T 441-2019, and the second-order resonance frequency was still within the range of pedestrian load frequency, which may still cause comfort problems. Test results show that the presence of people increases the damping effect of the structure.

Implementation of Eco-Industrial Park for Effectual Establishment of Circular Economy in Russia

In recent years, waste management has become a major concern in Russian cities. This can be addressed through the circular economy. Developing Eco-Industrial Parks (EIP) can be considered an innovative infrastructure of a circular economy. EIP is based upon the principles of industrial symbiosis involving the exchange of material and energy flows, sharing of infrastructural facilities, and provision of municipal utility and other services. Researchers have found that most industrial symbiotic interconnections originated spontaneously, the main driver being the increasing commercial benefits of such interchange. Still, the authors were able to identify pre-designed EIP through their examination of global practices. This paper proposes a five-stage methodological approach to EIP organization. This methodology was applied to create a model of an EIP in the Voronezh Region, one of the fastest developing regions in Russia. Implementation of this model is intended to help solve a set of environmental, economic, and social problems of a region. The approach to creating EIPs described in this study can be used in other places to improve resource efficiency and reduce waste disposal. Because Russia’s garbage disposal rate currently exceeds 90% per year, this is one of the country’s top sustainable development priorities.
