This project design is based on the location of UPFC for congestion management in the deregulated power sector and presents a nonlinear optimization problem formulation with UPFC to see the impact on transmission real and reactive spot pricing. The algorithm is designed using Matlab has been demonstrated on a IEEE 30-bus test system.
Fig. 1. Schematic diagram of UPFC.
The schematic representation of the UPFC is shown in Fig. 1. It consists of two voltage source converters and a dc circuit represented by the capacitor. Converter 1 is primarily used to provide the real power demand of converter 2 at the common dc link terminal from the ac power system.
LOCATION OF UPFC
The severity of the system loading under normal and contingency cases can be described by a real power line flow performance index, as given in the following:
REAL AND REACTIVE SPOT PRICING
The objective of pricing policy is to maximize the benefit of all the participants, that is, to maximize the consumers and producer’s surplus, subject to operational constraints. This is accomplished by setting the prices of real and reactive powers at each bus at a particular time equal to the marginal values of supplying and consuming real and reactive power at the same bus and at the same time, where the marginal values are determined by maximizing total surplus of utilities and consumers, subject to the operational constraints. Mathematically, the normal dispatch problem can be written as,
