In order to unlock the flexibility potential of energy consumers and prosumers, development market mechanisms for planning procurement is necessary. The authors propose a stochastic local solve grid issues such as voltage deviations congestion in distribution grid. Their proposed solution includes activation assets at consumers' premises, using design. They consider pooled design under demand uncertainty bidding process. Optimization models are used determine supply bids by system operator...

The increasing share of variable renewable energy sources creates a need for flexibility resources in the power system operations. This paper presents suggestions characterizing flexibility, including dimensions time, spatiality, resource type, and risk systems. We present interrelations between these dimensions, products, services, suitable market designs. In light this, we discuss TSO–DSO coordination optimal allocation.

This paper investigates cost-optimal operation of flexible electricity assets with a capacity-based power grid tariff involving subscription. The purpose this research is to identify the characteristics subscribed that promotes efficient network development through demand response. Using historical load data, we compare two consumers being billed by their individual versus combined and coordinated loads in two-stage stochastic program. frequency adjusting capacity level (weekly annually)...

The authors focus on a model for system operators that uses centralized scheduling of multiple flexibility assets and services to minimize the cost managing problems with grid congestion, voltages, losses. schedules using stochastic optimization AC optimal power flow in an active distribution network. novelty contribution lies its how dynamic capabilities resources are defined regard uncertainty is resolved model. impact studied by well-known quality measures from programming, such as value...

Procurement risk management (PRM) requires a good understanding and assessment of all potential risks. As the procurement industry mostly functions globally supply--demand chain forms dependency structure among interested parties, quantification risks related to suppliers gain importance. This study presents systematic PRM evaluate quantify commodity associated its suppliers. The probabilistic set up using total probability theorem on information collected tools, such as expert opinion,...

The authors provide a comprehensive overview of flexibility characterization along the dimensions time, spatiality, resource, and risk in power systems. These are discussed relation to assets, products, services, as well new existing market designs. argue that should be evaluated based on under discussion. Flexibility products services can increase efficiency systems markets if assets related taken into consideration used geography, technology, dimensions. Although it is possible evaluate...
