Maximizing Solar Energy Yield In Hybrid Grid-Solar-DG Industrial Application
Journal Title: American journal of Engineering Research - Year 2018, Vol 7, Issue 8
Abstract
In industries, Energy mix in different proportion is used. The main energy sources is from utilities and is conventional one (coal, oil, gas). Energy from DG sets, though conventional is used as standby or alternative source. Energy from conventional sources produces greenhouse gases and cause climate change. Considering importance of clean energy solar PV power (Ground mounted or rooftop) can be future alternative main energy source. Optimizing the hybrid Grid-DG-Solar and maximizing clean solar energy in the energy mix is a challenge. This research work has developed an energy mix algorithm for maximizing solar energy where it is injected in existing utility grid having standby DG sets energy source. The proportionality of the energy sources in the energy mix in supply side energy management is evaluated and equation established for stabilizing energy demand side energy management in view of maximizing solar clean solar energy in energy mix. Based on algorithm electronic hardware are developed for maximizing solar power of capacity 550 kW power in an energy mix of contracted load of –kW with stand by DG sets of -,- and – respectively. A control unitdeveloped is further tested in real time field operation in industry (latitude, Longitude) having optimum solar energy capacity for a day capacity with net metering system. The test results shows that the logic developed works accordingly with specific time lag provide in program for ‘online’ auto operations of supply side energy mix under stabilized load conditions. It is found that the solar PV power is consumed maximum in energy mix all the time when the grid is ON. It is also maximum when grid is OFF and DG throttles to its minimum (30% set by DG provisions)
