REVIEW PAPER ON HYBRID SOLAR WIND RENEWABLE POWER SYSTEMS
Abstract: Solar and wind energy have increased greatly in the past few years. In this study, we proposed a hybrid energy system that combines solar panels with wind turbines to replace traditional sources of electricity, such as thermal and hydropower. Renewable energy is becoming increasingly popular as an unrealistic alternative source of electricity to traditional power generation. Electricity demand is growing every day, and non-renewable energy alone cannot be met. Renewable …

Determination of Lightning Arrester Value to 11/0.415 KV Distribution Substation Transformer on Unprotected Overhead Lines
Abstract: Lightning is among the major causes of outages in distribution networks. Over-voltagesarising from lightning strokes disrupt electricity supply by causing damages to transformersand other sensitive equipment in the network. Transformers are a critical part of everydistribution network and serve the purpose of stepping down electrical energy to levelssuitable for consumption by the end users. Adequate protection of transformers and otherdistribution equipment against lightning is a proactive measure to achieve high …

Economic Load Dispatch: A Review
Abstract: In this paper, the problems related to economic load dispatch (ELD) have been discussed. The ELD problem can be conceived as an optimization problem of minimizing the total fuel cost of all generating units while satisfying the demand and losses. The ELD problems have non-smooth objective function with equality and inequality constraints. The economic dispatch problem means the real and reactive power of the generator varies within the certain limits …
