Task 1 1. Describe the power system. The power system of choice which best suits this project is “Hybrid Power System”. This system employs combination of Off grid renewable energy technologies among which we are going to use a combination of Solar, Wind, Hydropower and for an emergency back up a gasoline/diesel generator is also provided.
On a macro scale the Hybird system work in three phases, production, Power electronics and Consumption. The production is done by the Renewable Energy system, stored by batteries and in case of backup by generator. Then the Power Electronics regulates the supply and transmission of the power to the appliances where the load is required. This figure below shows working of a Hybrid System. To meet the base demand of 100KVa at a power factor of 1, thus energy requirement of 100KW we will include a system setup which will include three complete 20 kW solar panels. The photovoltaic systems that are available in the market are of 20kW, 50 kW and 100 kW and thus it has been concluded that three 20 KW panels are used. In case of failure of one, the system does not collapse completely. The picture and detail configuration of similar system with reference is given in the Appendix 1. The next component in the Hybrid system’s energy input is the wind turbines. ...
