In [111, 112], a two-stage method was used to solve the optimal capacitor placement problem. First, the power loss index (PLI) in and the LSFs in were utilized to determine the high potential buses for capacitor placement.
The proposed procedure using the multistage method to find the optimal placement of capacitors is applied on three standard radial distribution systems. These test systems are 10-bus, 34-bus, and 85-bus standard distribution test systems. The results are compared with those obtained using other reported methods.
Bhattacharya and Goswami used the fuzzy-based method for the identification of probable capacitor nodes of the radial distribution system, while the simulated annealing (SA) technique was utilized for the final selection of the capacitor sizes.
These analytical expressions can be employed for accurately solving the capacitor allocation problem. The results show that the proposed approach is accurate with respect to the exact solutions computed by exact search-based methods and efficient compared with existing methods.
Specifically, two analytical closed-form expressions are introduced to determine the optimal number, locations, and sizes of multiple capacitors. The first analytical expression computes directly the optimal sizes of multiple capacitors where it is employed for the optimal sizing of capacitors for all possible combinations of locations.
Reconfiguration and capacitor allocation procedures in radial electrical distribution systems (EDS) are attractive alternatives for technical losses reduction , . The reconfiguration problem consists in determining a radial and connected network topology, through the definition of the maneuverable switches states (open or closed).

Meaning of capacitor "× 2" symbol on data sheet schematic
I''m looking at the data sheet for an Analog Devices LTC7149 step-down regulator. On the first page there''s a "Typical application" circuit diagram that shows a capacitor on the V OUT-output that''s labelled "22µF × 2".. Does this mean that the circuit should contain two 22 µF capacitors (presumably in parallel), and not just the one that is shown on the drawing?
