Glossary

Transmission System Operator (TSO). Transmission System Operator is a natural or legal person responsible for operating, ensuring the maintenance of and, if necessary, developing the transmission system in a given area and, where applicable, its interconnections with other systems, and for ensuring the long-term ability of the system to meet reasonable demands for the transmission of electricity.[1]
Balancing Service Provider (BSP). Balancing Service Provider (BSP) in the European Union Internal Electricty Market is a market participant providing balancing services to its Connecting TSO, or in case of the TSO-BSP Model, to its Contracting TSO.[2]
Mixed Virtual Enabled Unit (MVEU). Aggregate (also known as industrial districts) consisting of production, consumption and storage plants that participate in the `#ElectricalFlexibility` processes, governing the use of energy according to the actual power needs. Storage systems functional to electric mobility are also part of the MVEU pilot project, as these are considered to be completely comparable to other storage systems.[3]
Distribution System Operator (DSO). Distribution System Operator (DSO) in the European Union Internal Electricity Market is legally defined in Article 2(29) of the Directive (EU) 2019/944 of the European Parliament and of the Council of 5 June 2019 on common rules for the internal market in electricity (recast), and stands for a 'natural or legal person who is responsible for operating, ensuring the maintenance of and, if necessary, developing the distribution system in a given area and, where applicable, its interconnections with other systems, and for ensuring the long-term ability of the system to meet reasonable demands for the distribution of electricity.[4]
ISOPROD. Electric load profile of the Consumption Units (CU) (mapped within the industrial-type production process) built respecting all the constraints of the process itself, i.e. the production performance index (Qty/h).
ISOCONF. Electric load profile of the Consumption Units (CU) (mapped within the supply chain responsible for providing environmental services) built respecting all system constraints, i.e. the environmental conditions to be supplied (*temperature, humidity,…*).

Introduction

To realize the #ElectricalFlexibility:
  • which technology?
  • what architecture?
  • which platform?
The question is not which, but how this is achieved by avoiding tactical approaches that introduce other issues (e.g. batteries) instead of providing a system solution.
How to create the #ElectricalFlexibility:
  • virtualize the electrical #Demand, through the #Digitization process;
  • optimize the consumption profile (#Profiling) of the Consumption Units (CU), both single and aggregated (MVEU / industrial districts);
  • execute the consumption program (#Baseline) scheduling (#Scheduling) the activities of the Consumption Units that compose it;
  • build the map of the CUs, within the #Baseline, which are proposed (pay-as-bid) to the TSO to solve the problems of Network imbalances (#Balancing) through modulating its consumption and respecting all the constraints of the system and the program itself;
  • sell the #NegaWh the modulation program of the CUs, which are proposed as resources of #ElectricalFlexibility.
#NegaWh measures the flexibility (energy to "increase in consumption "and / or" decrease in consumption ") of the CU, within the baseline, which are proposed to market (pay-as-bid) as resources for services reserve (primary, secondary, tertiary) in dispatching sessions, in order to resolve the imbalances in the electricity grid.

A further step forward, to realize the flexibility's paradigm, is to build, through the #Digitization process, the services that maximize the values related to the #ElectricalFlexibility making the Consumption Units ready to be used from the TSO as resources to be used in the stock market sessions (#FlexibilityReady).
The #Digitization transforms electrical energy from commodities into technological services (#EnergyAsAService), aiming to eliminate the risks associated with non-compliance with the electrical programming of the CU and to maximize the opportunities related to its own #ElectricalFlexibility. The new digital energy services have the following objectives:
  • reduce the marginal costs associated with its use;
  • optimize consumption;
  • maximize the revenues able to pursue by participating in the #ElectricFlexibility market.
The push towards the energy service model is given by the following market trends:
  • De-carbonization of the economy, i.e. maximization of renewable energy and the minimization of its marginal cost;
  • Digitization: the total interconnection of decentralized, disintermediated and distributed systems and data, according to the #Blockchain model. The #Digitization opens up the values and methods of physical and mathematical optimization and new business models to the world of energy.
The #EnergyAsAService model focuses on the specific satisfaction of the Customer by creating new economic values in harmony with the objectives defined by the #EnergyTransition:
  • Earning from the Grid: economic enhancement of the #ElectricFlexibility extracted from the CU and that the Customer can offer to the electricity system;
  • Minimization of marginal costs: optimization of electricity consumption profiles;
  • Economic and environmental sustainability of the production cycle.
