Load Shedding Technique for Maintaining Voltage Stability

Recently, energy and power industries have under-went considerable changes, because of intervention of DG’s in the existing conventional system, the operational, management, and control of the power system is becoming ever so more complicated and tedious along with several challenges. The earlier distribution structure has under-went huge modification in the past few years as power systems are no more regulated by a single hand. The involvement of variable large and small private players has complicated the situation further. The system operator is facing more challenges as now the flow of power in both the directions, i.e., from generator end to consumer end and vice versa. The spatially Distributed Generation (DG) has provisioned facility of clean energy and reduction of emissions safe guarding environment and has considerably improved the efficiency and performance of power system. However, inclusion and integration of DGs in the conventional power system have side effects towards reliability of the system. The introduction of DGs gives rise to poor power quality, faulty operation of protection systems or devices, and may even lead to voltage sag or swell, all of which are undesirable effects of penetration of DGs.
