Incorporating indirect costs into energy system optimization models: Application to the Dutch national program Regional Energy Strategies

Energy system optimization models are widely used to aid long-term investment decision-making for energy systems. From a socio-technical system viewpoint, existing models focus on the cost modeling of the technical subsystem, while the indirect costs of the social subsystem are not often modeled. This paper incorporates indirect costs into such...

Symmetric Kinetostatic Behavior From Asymmetric Spatially Curved Beams

A cantilevered rod's endpoint has a symmetric stiffness profile throughout its range of motion. Generally, this is not the case for spatially curved compliant beams, particularly if they are asymmetric, i.e., their fixation is not in the symmetry plane of their endpoint operating field. This paper discusses a technique for obtaining symmetric...

Asymmetric Spatial Beams with Symmetric Kinetostatic Behaviour

A method to achieve symmetric kinetostatic behaviour in an extensive working range at the endpoint of an asymmetric spatial beam, using cross-section optimization, is presented. The objective function of the optimization is defined as expanding the beam working range to the desired region, simultaneously maximizing symmetric behaviour in it....

A spatially explicit planning approach for power systems with a high share of renewable energy sources

Variable Renewable Energy Sources (VRES) are characterized by intensive land-use and variable production. In existing optimization models that minimize the total cost of the energy system, location-specific VRES production profiles are often used to estimate VRES potential, but land-use and land cover aspects have been largely ignored. In this...

Optimization modeling of regional energy systems considering coordination mechanisms

Dutch regional municipalities increasingly take an active role in the transition to more sustainable and autonomous energy supply systems, using local energy sources like wind, solar and biomass. The ambition, on the one hand, concerns how an optimal local energy supply system can be designed such that local energy targets can be realized with...

Design and optimization of a general planar zero free length spring

A zero free length (ZFL) spring is a spring with special properties, which is commonly used in static balancing. Existing methods to create ZFL springs all have their specific drawbacks, which rises to the need of a new method to create such a spring. A method is proposed to design planar ZFL springs with specified stiffness (250–750 N/m)...

Local Alternative for Energy Supply: Performance Assessment of Integrated Community Energy Systems

Integrated community energy systems (ICESs) are emerging as a modern development to re-organize local energy systems allowing simultaneous integration of distributed energy resources (DERs) and engagement of local communities. Although local energy initiatives, such as ICESs are rapidly emerging due to community objectives, such as cost and...

Energy Based Error Formulation for Optimizing Compliant Joint Parallel Manipulators

The conversion of a Rigid Body Parallel Manipulator to a Compliant Joint Parallel Manipulator introduces compliance in the system. The configuration of the compliant manipulator will differ from the configuration described by the rigid-body kinematics due to the off-axis compliance, and hence off-axis deflections, of the Compliant Joints. In...
