The problem of optimal choice of fixed and switched capacitors in radial distributors with distorted substation voltages is formulated and solved by decomposition through isolated subproblems. The maximum sensitivities selection (MSS) method, which is used to solve the optimisation problem of the subproblems with discrete variables, is proposed.
Recycling capacitors is a way to keep old aluminum, steel or iron out of the waste stream and turn it into new uses. Although most local recycling pickups don''t take capacitors, many metal recyclers do. Because capacitors are meant to store power, you''ll have to follow safety steps when removing one from the electronic device that contained it.
