This paper proposes a new method to find the capacity of a future wind farm regarding several limits of the grid system: voltage stability limits, thermal limits, voltage limits, load tap changing limitation and generator power output limitation. The method combines the optimization method and a...

The paper describes modern wind power systems, introduces the issues of large penetration of wind power into power systems, and discusses the possible methods of making wind turbines/farms act as a power source, like conventional power plants in power systems. Firstly, the paper describes modern...

Under the majority voting rule, a system of universally available vouchers (UV) is politically less feasible than a system of selective vouchers (SV) confined to families with incomes equal to or less than median voter income. After the introduction of UV, public expenditure on education will...

This paper develops an efficiency-wage model of steady-state equilibrium with labor-augmenting technical progress, and uses the model to explore the long-run relationship between unemployment and growth. The rate of productivity growth is either specified exogenously or determined endogenously...
