    -> Produce power
  2. Transmission (Downstream)
    -> Transmit power over long distances
  3. Distribution (Downstream)
    -> Deliver power locally to customers

Q

Regional transmission organization

A regional transmission organization (RTO) in the United States is an electric power transmission system operator (TSO) that coordinates, controls, and monitors a multi-state electric grid

The transfer of electricity between states is considered interstate commerce, and electric grids spanning multiple states are therefore regulated by the Federal Energy Regulatory Commission (FERC)

An independent system operator (ISO) is similarly an organization formed at the recommendation of FERC. In the areas where an ISO is established, it coordinates, controls, and monitors the operation of the electrical power system, usually within a single US state, but sometimes encompassing multiple states.

RTOs typically cover a large geographic area

67
Q

Level of DSO concentration

The complexity of the system to move electric power from the point of production to the point of consumption combined with variations in weather, generation, demand and other factors provide many opportunities for the quality of supply to be compromised.

To function in their intended manner (i.e. without significant performance losses) distribution grids require good quality electrical power with following characteristics: ?? (4)

A

stable continuity of service

low harmonic content

low variation in voltage magnitude
(-> voltage magnitude: Spannungsgröße)

low transient voltages and currents
(-> geringe transiente Spannungen und Ströme -> Transiente Spannungen und Ströme sind wohl kurzzeitige, vorübergehende Zustände in einem elektrischen System, die durch plötzliche Änderungen, Schaltvorgänge oder andere Störeinflüsse verursacht werden können. Ein System mit niedrigen transienten Spannungen und Strömen ist weniger anfällig für Störungen oder Schäden durch solche vorübergehenden Ereignisse)
