Definitions

  • It relates more particularly to a method for automating the detection of reactive energy and thus allow the optimization of energy consumption implemented in power grids.
  • the third step is a diagnostic step in which the compensation algorithm calculates the power factor and triggers, if necessary, an alert, in particular according to the contract linking the electricity supplier and the user who has the loads. electric.
  • An example is the one shown in Figure 4: the recommended value of the power factor cos ⁇ located in the range (0.95, 1) is considered as the optimized situation. Outside this range, the compensation system is activated either under manual control or automatically. In order to ensure the stability of the compensation system, the duration of the power factor outside this range is also considered.
  • the third mode consists of global compensation: the compensation equipment is installed at the head of the electrical loads and provides all the charges for the compensation. They help relieve the transformer installed by the electricity supplier.
  • the phase shift can vary randomly due to the collective effect of all connected machines. All stages are automated and can be controlled in real time and remotely.
  • the parameters can be programmed upstream to actively compensate for the use of electrical loads. According to the user's requirement, the parameters may be different at the requested time, such that the range of the power factor cos ⁇ may be changed remotely so as to present, for example, a different value of the afternoon with the morning one and respectively.
  • Our proposal is to propose a compensation method referred to the network based on a distribution system. Due to the charge compensation, the individual compensation data is obtained for the loads of each SME-SMI user. And with these data, compensation can be made with respect to the public electricity grid by piloting each user. With actuator sensors directed from a cloud-based technical platform, it is possible to control the reactive energy consumption of end-users. It is also possible to operate according to the own constraints of the distribution network that it is public or that it concerns a network of different users.
