Superordinate clear notion of the work packages and their correlation to the context of the project target.
To ensure a secure and efficient transport process as well as cross-system interoperability, the development of an integrated data infrastructure is necessary. Hence is the goal of the work package the processing and integration of the operation- and process data from WP1 as well as the development of a cloud-based platform which is tailored to the requests of a raw material extraction plant. The core data of the extraction plant- and machine components which were identified during the process of analysis are yielded and the relevant ressources are tethered via standard ports for providing the measured and state data. he processed and structured data and the developed cloud platform are synced. Hereby the availability of all of the required data and information within the project syndicate is ensured. Additionally the charging management, the production planning and the fleet management of the electric-autonomous transport vehicles shall be optimized through a AI-based process.
In this Work Package operational modeling is realized through the foundation of the previous process analyses in the factories of the demonstration phase as well as the gathered and constantly plotted data. By using the operation and process data and the forecast model the requirements on the heavy-duty transport machines in combination with the requirements on the coupled accumulator and energy systems as well as on the infrastructure can be determined. Likewise, the provision and accumulation of energy considering the usage by operation as well as the availabilities of the energy sources and the energy grid have to be construed.
Target is to complete the modeling of the relevant components of the entire system and to make the results available on the cloud-based platform. The digital twin is finished by this point for the predefined use case.
In the Work Package the optimization of design and usage is realized on the base of the previous Work Packages. These are especially optimal usage of the electric-autonomous transport vehicles, the battery capacity and the charging management are covered. WP 4 begins with a design phase, in which the total system is prepared for the demonstration. In the further course follows the progressive optimization of the entire system. In the further course follows the progressive optimization of the entire system.
The design of the electric-autonomous transport machines is mainly limited by the requirements of continuous operation and amounts of raw material extraction designated in plant engineering. The focus in lays on the design and optimization of the utilization profile of the electric-autonomous transport vehicles. The optimal charging time, power and cycles of the vehicles are computed continuously computed and are distributed by recommendations of the subsequent use.
Parallel to the design and optimization of the usage of the electric-autonomous transport vehicles there is to realize the design optimization of the belonging vehicle batteries. The optimization of the battery systems regarding their technical design and dimensioning is primarily realized for the existing use case. Later these results are combined with the ones from WP4.1. This enables the possibility to adapt the battery usage to the divergence of the theoretical and practical operation state.
As an additional independent variable of the design and optimization regarding a totally optimal system of the raw material extraction company there has to be taken into account the mains connection and the possibilities of local electricity generation as well as flexibility of power supply at the location. These higher level design and optimization aspects regarding the location or the energetic circumstances is realized. Target is integrating the rather complex and multi criterial decision problem of efficient energy production, usage and storage in the transport process and dividing in relevant and systemically separable components. The reason is, that taking into account time and resources, an isolated optimization is more expedient than an optimization of the the entire system with insecurities regarding the validity of the result of the optimization.
The enormous demonstration and analysis of the systems, processes and infrastructure in the quarry of Eigenrieden lay the foundation of future innovations and optimizations of extraction hauls to achieve a more sustainable and efficient production. The use case Altertheimer Mulde of the Knauf Gips KG shall serve as a greenfield project, on which the results of the other two use cases can be transferred.
To demonstrate systems and subsystems in the quarry of Eigenrieden and the sand mine of Nivelstein there are projected the production relevant transport chains and processes. Foundation of the business and process oriented transformation steps in this Work Package are the results from WP4. Part of this is the realization of the transport way management conceived in WP4 and the charging infrastructure necessary for the use of electric-autonomous transport vehicles. After the transformation the changes up to electrical-autonomous transport are made as a demonstrator. During the demonstration phase all of the processes are analyzed and digitally worked up. The following steps are taken hereby:
The electrification of transport vehicles in raw material extraction plants gains relevance due to the previously examined growing relevance of sustainability as well as environmental and health protection. The introduction of electrical transport vehicles can help reducing the emissions and the dependency on fossil fuels. Nevertheless, these following problems are identified as obstacles of a successful realization:
The acquisition costs for (battery) electric transport vehicles as well as their belonging infrastructure are usually higher as the costs of usual Diesel-powered models. This is a financial burden for raw material extraction companies, especially for the smaller ones with limited budget.
The electrification does not only require the exchange of combustion engines with electrical powertrains, but also the adaptation of infrastructure and operating procedures. It is important to understand the specific requirements and challenges of a step-by-step electrification to ensure a smooth integration. A detailed analysis of the operational applications, energy demand and infrastructural requirements is necessary to identify and realize the necessary adjustments.
The electrification can have radical impact on the complete operation, including the processes and the infrastructure. It is important to understand the potential changes and to take action to beware of possible problems. This makes a extensive analysis and evaluation of the actual operation processes inevitable.
The development of the transformation concept has the same global target, which is to realize a systematical and modular conception for the transformation from conventional operation models up to an electrified transport in raw material extraction. Therefor firstly the requirements of the raw material extraction companies onto the electrical transport vehicles are identified. Subsequently the effect of the electrification on the transformation of raw material extraction companies are analyzed at the instance of the use case companies. Finally the derivation of guidance from the evidence of the use cases of the project on the electrification of raw material extraction companies is done.
With the aid of this transformation concept it shall be possible in the future to promote the electrification of raw material extraction companies in a comprehensible, easier and stronger way.
Target: Conservation, Documentation, Evaluation and utilization of the project results during the runtime of the project and in the further course. Additional target is the determination of the potential impact of the project results on the raw material extraction industry.
In this Work Packages the Syndicate ensures a joint evaluation and utilization of the gained results. This happens through continuous project meeting and if necessary the emerge of CoWorking Spaces of temporary nature at the demonstration location as well as a conclusive joint documentation of the results. For the scientific utilization the results shall be presented on national and international conferences by the academic partners and be discussed by the professional audience. Young scientist are being promoted through integration in the work of the research project and theses possibilities. The project results have direct influence on the further development of the economic partners, which leads to the later goal of commercial utilization of the results. Inter alia in the area of sustainable, CO₂ neutral raw material extraction there is by now already a significant interest at the market (Customers of the extraction companies) determined, which makes the foundations for the further development and commercialization of the physical systems and digital services. With this the possibilities emerged by the technology as well as critical factors for realization and commercialization are defined.
Target of this work package is the integration of internal and external actors during the runtime of the project to assure a continuous communication and sustainable project development.
In Working Package 8 the communication of the project modernizations and results to relevant actors is assured. Internal actors (e.g. mine companies and staff members) as well as external actors are included during the complete runtime of the project Thus the support of the project and its goals from the syndicate itself but also from the public, authorities, mining authorities and co-operatives is assured. The inclusion of the project partners assures the acceptance as well as the usage of the project results and the technical and structural changes beyond the runtime of the project. Actions from WP 8 can be the formation of a council of experts, staff workshops and the creation of web presences for external representations.
Within the frame of the project, regular meetings of the entire syndicate take place at the different locations of the project partners. In these meetings, important decisions and approaches are discussed and set. Additionally, topically focused meetings and workshops take place, in which the partners converse their approaches in an inner circle.
