In this paper a novel non-linear optimization problem is formulated to maximize the social welfare in restructured environment with generalized unified power flow controller (GUPFC). This paper presents a methodology to optimally allocate the reactive power by minimizing voltage deviation at load buses and total transmission power losses so as to maximize the social welfare. The conventional active power generation cost function is modified by combining costs of reactive power generated by the generators, shunt capacitors and total power losses to it. The formulated objectives are optimized individually and simultaneously as multi-objective optimization problem, while satisfying equality, in-equality, practical and device operational constraints. A new optimization method, based on two stage initialization and random distribution processes is proposed to test the effectiveness of the proposed approach on IEEE-30 bus system, and the detailed analysis is carried out.

The analyses and conclusions presented in the article are based on the results of qualitative panel surveys conducted among large indigent families in the years 2013 to 2014 and in 2017. The survey attempted to answer the questions of whether and to what extent the implementation of a pro-family policy in Poland in 2016 influenced the situation of large families receiving institutional social aid. On what do these families spend the payments received from the Family 500+ programme? Has their new economic situation favoured their activation or increased their ability to manage? Could the programme, in consequence, hinder or limit the intergenerational transmission of poverty? The author concludes that in fact the effects of financing large families differ from those that were intended. The programme, which was intended to be pro-natal, has acquired the nature of social aid payments. It has improved the material situation of many families, but it has not sufficiently contributed to changing ways of thinking about the children’s futures, which would contribute to limiting the processes of inheriting poverty.
