The paper highlights the main characteristics of Virtual Power Plants (VPP). A Virtual Power Plant is a cluster of distributed generation units (such as photovoltaic power plants, wind turbines or small hydro) and any other sources of power that can cooperate together in the local area, and are controlled by a central control entity. An analysis of a VPP that is used to cover the load is performed for the whole day. The distributed generators from the VPP have different merit orders and outputs. Another analysis is performed for a power system in which a VPP is added. The analysis compares the power flow for the situations with and without the VPP.

“…V IRTUAL POWER PLANTS (VPP) are expected to play an important role for the integration of distributed energy resources (DER) into the energy grid in the near future [1], [2]. Within the upcoming discussion on smart grids, VPP are handled as a promising concept for bundling decentralised capacities by means of IT-infrastructure.…”

The sets of feasible load schedules that distributed energy resources are able to operate, jointly define the search space within many virtual power plant optimization tasks. If a centralized approach is considered, a central, single scheduling unit needs to know for each energy resource what schedules comply with all given constraints, because only these are operable and might be taken into account for optimization. As many constraints depend on state or time, sets of currently operable alternatives have repeatedly to be communicated to the scheduler in order to avoid central modeling of each single resource.We here present a support vector based approach for learning a highly efficient geometric representation of the space of feasible alternatives for operable schedules. This description is communicated to the scheduler and the encoded information implicitly contains all constraints and therefore makes their modeling dispensable at scheduler side.

Abstract. In this work we present an adoption of systems engineering methodology for design and assessment of a Virtual Power System (VPS). The VPS has been defined as an aggregation of distributed energy resources, consumers and storages which can operate autonomously, and is presented to the power system as a single unit in technical and commercial terms. The complexity of these critical systems is tackled by means of systems engineering. We have applied our approach in scope of a research project AlpEnergy.Keywords: systems engineering, modeling, SysML, VPS; assessment. Introduction and BackgroundIn the present work based on achieved results in the course of the international AlpEnergy project we provide description of a methodology used for design, implementation and assessment of Virtual Power System (VPS). VPS integrates, manages and controls distributed energy generators, electrical vehicles (and other controllable loads) and storage capacities and links their technical operation to the demand of consumers and the energy market. Detailed VPS description providing basic definitions and explanation of the concept is presented in [12,14]. One of the main challenges of the project is considered to be tackling of multidisciplinary nature of VPS concept and developing of a model of the supporting ICT structures which are crucial to critical infrastructures. Moreover, an evaluation strategy for pilot implementations was supposed to be developed. To cope with the challenge we have adopted systems engineering methodology already proven as a very efficient instrument to tackle complexity of different heterogeneous systems and different technical backgrounds of stakeholders [8]. The methodology is based on instruments provided by SysML modeling language -widely accepted UML profile for modeling of complex heterogeneous systems. The methodology is presented in details in [1], [13] while similar approach is also applied in [3]. In this work we focus on assessment of different project implementations showing how proposed methodology can be used for that purpose.VPS concept supposes a flexible structure that embraces widest set of technical and commercial issues. Furthermore, VPS model has to absorb all the changes and adaptations in the system and its environment and for that reason has to be constantly
