EIFER engineers chose AnyLogic simulation modeling to determine how localized systems with various novel features could be implemented. Local energy grids are often more at liberty to accommodate power storage, renewable energy sources, and smart technology related to demand forecasting. Localized energy systems, unlike classical ones, do not need to transmit electricity over long distances, as they are located close to the load they serve. It works on the decentralization of energy systems in various territories and promotes renewable energy sources. 23, pg.The European Institute for Energy Research (EIFER) is a joint research center created by Karlsruhe Institute of Technology and EDF. Simulation and optimization model for electrical substation construction, ITcon Vol. However, the model is limited to the scope of civil works, without considering the electromechanical works and the effect of risk factors on time and cost.Įlectrical substation, construction, simulation, optimization, genetic algorithm, time, costįayed R A, Ezeldin A S (2018). An analysis to determine the effect of each resource on reduction in cost was presented. The models prove efficiency by attaining a reduction in model time units between simulation and optimization experiments of 10.25% and reduction in total cost of 4.7%. The models were then tested on a real case study in Egypt. The model is then optimized to mainly minimize the project duration using a parameter variation experiment and a genetic code implemented using Anylogic platform. Each zone- model describes the execution process of each building in the zone, the time consumed, percentage of utilization of equipment and manpower crews, amount of materials consumed, total direct and indirect cost. Each zone includes a group of buildings related to the same construction area. The model is divided into three zones working in parallel to each other. The model is built on Anylogic software using discrete event simulation method. The input data include bill of quantities, resources breakdown, maximum available resources, production rates, unit cost of resources and indirect cost. In order to address the aforementioned adversities, this paper takes the initial steps and presents simulation and optimization model for the execution processes of civil works for an electrical substation using a data base excel file for input data entry. The construction industry is becoming increasingly competitive over the years, whereby the need to continuously find ways to improve construction performance. The scope of civil works includes construction of several buildings divided into parallel and overlapped working phases that require variety of resources and are generally quite costly and consume a considerable amount of time. Construction of electrical substation includes civil works and electromechanical works. 215-242, Simulation and optimization model for electrical substation construction submitted:ĭepartment of Construction Engineering, School of Science and Engineering, American University in Samer Ezeldin, Professor and Chairman,ĭepartment of Construction Engineering, School of Science and Engineering, American University in of the most complex construction projects is electrical substations.
