“…Whenever congestion situations are detected, congestion management must be undertaken in order to deploy a noncongested dispatch (re-dispatch) [12], [13], [14]. For this purpose, we propose the use of the algorithm presented in Figure 2.…”

Locational Marginal Prices (LMP) are important pricing signals for the participants of competitive electricity markets, as the effects of transmission losses and binding constraints are embedded in LMPs [1],[2].This paper presents a software tool that evaluates the nodal marginal prices considering losses and congestion. The initial dispatch is based on all the electricity transactions negotiated in the pool and in bilateral contracts. It must be checked if the proposed initial dispatch leads to congestion problems; if a congestion situation is detected, it must be solved.An AC power flow is used to verify if there are congestion situations in the initial dispatch. Whenever congestion situations are detected, they are solved and a feasible dispatch (re-dispatch) is obtained. After solving the congestion problems, the simulator evaluates LMP.The paper presents a case study based on the the 118 IEEE bus test network.

“…Voltage security has been reported to be very crucial; along with the urgency to deliver smooth and secure electricity to the customer [4]. Violation in voltage limit can drive the system to initial slow, followed by the progressive decrease by a rapid decline in voltage magnitude at various buses [5].…”

This paper presents a voltage stability assessment based approach to determine the congested line with optimal sizing and location. FVSI, a voltage stability index is chosen as the indicator for congested line identification, while particle swarm optimization technique (PSO) is used for optimal location and sizing of FACTs devices installation. Congested line is identified by increasing the reactive load at chosen load buses until they reach the maximum loadability level. PSO is applied for identifying the optimal location and sizing of FACTs devices as the compensating device. Results obtained from the implementation on IEEE 30 Bus RTS revealed that the proposed technique can manage the congestion subject to various disturbances.
