In this paper Spontaneous Process Algorithm (SPA) is proposed to solve
optimal reactive power problem. Formulation of the projected algorithm
is done by imitating the process done during nuclear fission and fusion.
Every item of a nucleus attribute symbolizes each solution variable.
Sequence of operators directs the nucleus and in order to avoid the
local optimum it will imitate the dissimilar condition of reaction. In
the exploration space nucleus symbolizes the variables and potential
solution. Levy flight has been intermingled in the procedure to enhance
the diversification and intensification in the search. Spontaneous
Process Algorithm (SPA) has been tested in standard IEEE 14, 30,
57,118,300 bus test systems and simulation results show the projected
algorithm reduced the real power loss comprehensively and there is
increase in percentage of reduction of real power loss.
