Trio-lattice scheduling for effective resource utilisation of solar energy to cater plead irrigation

Abstract

In actual practice, the most demanded agricultural loads (MDAL) are not being taken care of due to the scheduled power supply methodology practised by the present power distribution companies. Consequently, seasonal cultivations are affected due to insufficient availability of power supply. In this paper, the furnished result of a walk survey performed within an agricultural predominant area located in the vicinity of 33 kV/11 kV 5 MVA substation sited at lat. 13.62°N, long. 79.24°E and alt. 256 m confirms the above statement, i.e. about 62.12% of farming is affected due to insufficient availability of power supply. To address the concerns of the non-consideration of MDAL within the aforesaid expanse, a solar power generator of appropriate size, 103kWp derived based on the level of mismatch power attained by using ETAP software is proposed to erect near the utility grid and feed MDAL. Also, as a contribution, trio-lattice load scheduling methodology is introduced and applied to effectively utilise the generated electricity by scheduling the agricultural load points countered following the possible solar energy generation. Performance assessment indices: ADI, ERoS and ARoS are introduced to reconcile the effective utilisation of generated electricity by the proposed load scheduling methodology. The derived results and arrived performance assessment indices confirm that the proposed scheduling methodology could effectively utilise the solar energy resource and the concern system caters to the necessity of pleading irrigation.
