Der Energiebedarf einer Fabrik wird – neben den Energieverbräuchen der eingesetzten Produktionsressourcen – wesentlich von der zeitlich vorauslaufenden Planung beeinflusst. Mithilfe eines Energiebezugsplans sowie einer energieorientierten Produktionsplanung kann die kostengünstige Abstimmung von Energieangebot und -nachfrage einer Fabrik umgesetzt werden. Dabei gilt es, die Planungssysteme einer Fabrik zu befähigen, sich an die Bedingungen des Energiemarktes beziehungsweise der Erzeugung flexibel anzupassen.   The energy demand of a factory is determined by the specific energy consumption of the resources used as well as by advance production planning. An energy supply plan in combination with an energy-oriented production planning process aims for a cost-efficient adjustment of the energy demand and supply. The specific goal is to enable flexibility within the fatory’s planning systems in order to adapt the production processes to the volatile energy market and to the conditions of energy generation.

Angesichts steigender Energiekosten sowie eines zunehmenden Bewusstseins für nachhaltige Produktion ist es heute erforderlich, Zielvorgaben für den Energieverbrauch in der Produktionsplanung und -steuerung zu verankern sowie umzusetzen. Aus diesem Grund präsentiert dieser Artikel ein Verfahren für eine energieorientierte Produktionssteuerung, die auf der Basis von Energieflexibilität und Lastmanagement den Energiebedarf der Produktion mit einem begrenzten Energieangebot synchronisiert.   Due to rising energy costs and a growing awareness for sustainable production, it is now necessary for companies to establish targets for energy consumption in production planning and control. Therefore, this article illustrates a method for energy-oriented production control on the basis of flexibility and load management which synchronizes the energy demand in manufacturing with a limited energy supply.

Unternehmen, die ihren Energiebedarf gezielt am Energieangebot beziehungsweise den aktuellen Strompreisen ausrichten, können schon heute Energiekosten sparen und zur Stabilisierung der Stromnetze beitragen. Der Fachartikel zeigt auf, welche Datengrundlage ein produzierendes Unternehmen für einen flexiblen Energieeinsatz schaffen muss. Ausgehend von Anforderungen der energieorientierten Produktionsplanung und -steuerung wird dargestellt, wie die Datenerhebung, -auswertung und -nutzung gestaltet werden.   Companies which specifically align their energy demand with energy supply or current prices, can already save energy costs and contribute to the stabilization of the power grid. This article points out which data foundation a manufacturing company needs to create for a flexible use of energy. Based on requirements of energy-oriented production planning and control it is shown how the collection, analysis and use of this data can be organized.

The combined-cycle cogeneration facility on the central campus of Texas A&M University was analyzed for its present performance and an optimized mode of operation. The analysis was carried out using a plant Energy Optimization Program (EOP) that has been developed by Sega, Inc. The program uses Dither algorithms to match the energy demand and supply at each energy level (node), by choosing the lowest cost supplier among all the energy suppliers at the energy node. When this is done for all the energy nodes as the campus load varies throughout the year, one can determine the hourly and then the annual cost of operating the plant under both the existing and the optimized modes. The results were also compared with those obtained by using the Navy’s Civil Engineering Laboratory Cogeneration Analysis Program (CELCAP), and the agreement was within 5 percent. Comparison with actual costs produced an agreement to within 1 percent. Finally, certain recommendations are made as to a more cost-efficient mode of operating the present facility.

Due to the increase in energy demand, many countries suffer from energy poverty because of insufficient and expensive energy supply. Plans to use alternative power like nuclear power for electricity generation are being revived among developing countries. Decisions for installation of power plants need to be based on careful assessment of future energy supply and demand, economic and financial implications and requirements for technology transfer. Since the problem involves many vague parameters, a fuzzy model should be an appropriate approach for dealing with this problem. This study develops a Fuzzy Multi-Objective Linear Programming (FMOLP) model for solving the nuclear power plant installation problem in fuzzy environment. FMOLP approach is recommended for cases where the objective functions are imprecise and can only be stated within a certain threshold level. The proposed model attempts to minimize total duration time, total cost and maximize the total crash time of the installation project. By using FMOLP, the weighted additive technique can also be applied in order to transform the model into Fuzzy Multiple Weighted-Objective Linear Programming (FMWOLP) to control the objective values such that all decision makers target on each criterion can be met. The optimum solution with the achievement level for both of the models (FMOLP and FMWOLP) are compared with each other. FMWOLP results in better performance as the overall degree of satisfaction depends on the weight given to the objective functions. A numerical example demonstrates the feasibility of applying the proposed models to nuclear power plant installation problem.

As world demand for clean water increases, reverse osmosis (RO) desalination has emerged as an attractive solution. Continuous RO is the most used desalination technology today. However, a new generation of configurations, working in unsteady-state feed concentration and pressure, have gained more attention recently, including the batch RO process. Our work presents a mathematical modeling for batch RO that offers the possibility of monitoring all variables of the process, including specific energy consumption, as a function of time and the recovery ratio. Validation is achieved by comparison with data from the experimental set-up and an existing model in the literature. Energetic comparison with continuous RO processes confirms that batch RO can be more energy efficient than can continuous RO, especially at a higher recovery ratio. It used, at recovery, 31% less energy for seawater and 19% less energy for brackish water. Modeling also proves that the batch RO process does not have to function under constant flux to deliver good energetic performance. In fact, under a linear pressure profile, batch RO can still deliver better energetic performance than can a continuous configuration. The parameters analysis shows that salinity, pump and energy recovery devices efficiencies are directly linked to the energy demand. While increasing feed volume has a limited effect after a certain volume due to dilution, it also shows, interestingly, a recovery ratio interval in which feed volume does not affect specific energy consumption.

Renewable Energy Generation

Renewable energy generation is no more an alternative rather it becomes a choice for the power generation to meet the upcoming energy demand. Considering the non- renewable energy unavailability, as well as, the environmental impact, renewable energy should be the first choice. Most of the power generation in Bangladesh comes from nonrenewable energy and a noticeable amount of energy is imported from abroad. As a developing country, it is not cost-efficient and never ensures energy security. To ensure long-term energy security, it is time to shift power generation from nonrenewable to renewable energy generation. This paper presents an approximate calculation for the renewable power generating plant cost and returning year. The cost calculation is done in the context of Bangladesh.

Industrial enterprises are increasingly driven to tap the potentials of energy efficiency in existing and future production sites. The challenge is to identify cost-efficient levers for a low energy demand in the linked energy system of production machines and peripheral devices. Considering enabling technologies for energy efficiency and energy recovery in a cascaded energy network with energy storages this paper presents an approach towards energy and cost-efficient system configurations for production sites. An outlook will be given on the research center eta-factory for energy efficient factories at the PTW, TU Darmstadt.
