LOAD SHEDDING AND CAPACITOR PLACEMENT CONSIDERING DIFFERENT LOAD MODELS USING TLBO ALGORITHM
Load Shedding is an important scheme to prevent the collapse of the power system. However, this method is not able to stabilize the system all by itself, as well as frequency. Voltage also affects the stability of the network. This Matlab design is based on combination of load shedding and capacitor placement in distribution network. First identifying the weakest node and then applying the optimization algorithm to find the best solutions. Different models of loads such as constant power (P), constant current (I), constant impedance (Z), and composite (ZIP) are implemented, among them to identify the most effective load type that produces the optimal settlement for minimization loss reduction, voltage profile enhancement and cost savings. Teaching Learning Based Optimization (TLBO) algorithm is used in the design with Newton Raphson load flow simulated using Matlab 2020a/2021b version applied in standard IEEE 33 and 69 bus system with below cases.
1. Only Load Shedding
2. Only Capacitor Placement
3. First Load Shedding then Capacitor Placement
4. First Capacitor Placement then Load Shedding
5. Simultaneous Load Shedding and Capacitor Placement
