Shadow Pricing of Electric Power Interruptions for Distribution System Operators in Finland

Abstract

Increasing distributed generation and intermittency, along with the increasing frequency of extreme weather events, impose a serious challenge for the electric power supply security. Understanding the costs of interruption is vital in terms of enhancing the power system infrastructure and planning the distribution grid. On the other hand, customer rights and demand response techniques are further reasons to study the worth of power reliability. In this paper, the authors make use of directional distance function and shadow pricing method for a case study from Finland. The aim is to calculate the cost of one minute of power interruption from the distribution network operator perspective. The sample consists of 78 distribution network operators from Finland with cost and network information between 2013 and 2015.

Possibility to Apply Strontium Aluminate to Produce Light‐Emitting Plants: Efficiency and Safety

“…[2] However, 14.8 % of the world's population lacks access to power energy. [3] One alternative method that might provide light in areas without electricity, is light-emitting plants (LEPs). This technology has been interesting technology since 1986 [4] because if plants can provide light, it can benefit many people.…”

Changing the regulations for regulating the changes: From distribution system operator (DSO) to electricity distribution stakeholders’ organization (EDSO)

“…Although these models facilitate the ACs participation in the electricity market, they are not unbiased enough and do not address the concerns of discrimination and monopoly, specially in the presence of high penetrated ACs. 15 The common aspect of all these models is that, although they all emphasize the need to evolve the future EDN operator, they are still influenced by the dominance of the current DSO model. However, due to the ever-emerging ACs and their growing commercial interests, their conflict of interest with the DSO is increasing and the vertical unbundling of DSO is imminent.…”

“…This model benefits from supportive policies based on social welfare improvement and is rather away from the for-profit approach. 15 But the operator in this model suffers from monopoly. Although these models facilitate the ACs participation in the electricity market, they are not unbiased enough and do not address the concerns of discrimination and monopoly, specially in the presence of high penetrated ACs.…”

Innovation in regulated electricity networks: Incentivising tasks with highly uncertain outcomes

“…Therefore, the role of the grid is evolving beyond just supplying electricity to consumers (Poudineh et al, 2015). There are multiple pathways here but one scenario envisions the electricity network as a platform that also maximises the value of grid edge technologies such as distributed generation, storage, energy efficiency, demand response and electric vehicles (EVs) (Küfeoğlu et al, 2018). A new paradigm (including a technical, regulatory and business model) is required at grid level to integrate disruptive technologies, find new ways of operating to meet customers’ expectations and facilitate grid edge transformation.…”
