—This paper proposes a pricing system for power system security in deregulated electricity market that includes voltage stability constraint in a multi-objective OPF problem. The OPF maximizes social benefit, as well as the distance from the voltage-collapse point. While pricing system security, ancillary service such as reactive power has been included.(More)
Deregulation and restructuring of power system and introduction of distributed generation (DG) increased the importance of loss allocation to determine the tariff efficiently. This paper presents a new method based on proportional sharing; consistent with power flow while considering the radial system structure. The method composed of two steps. In the(More)
Restructuring of power system and the introduction of demand side management has changed the present scenario of power distribution system. Load management during peak hour is important for utilities due to rise in energy cost. Utilities have considered demand side management in their strategic planning without further constrictions on the level of customer(More)
