Abstract

Solar Energy Management for Agriculture and Rural Transformation (SMART) A SMART methodology (SM) is developed to provide cost effective and more reliable electric power supply to cold storage, irrigation pumps, and local loads. The effective operation of multiple sources in on-grid as well as in off-grid mode is possible with SM. The SM is a coordinated operation of sources, ESSs, loads, etc to provide electric supply. It provides electric power at a low cost. Effective power management is possible in SM. It is based on actual available power in individual sources and local load demand. In the SM technique, power references are estimated for power exchange with the conventional grid. It also calculates actual load demand (critical and noncritical) in the system. This information is communicated to SM smart load management through communication links. The SM provides various services such as monitoring of cold storage and irrigation system, estimates per unit cost, utility grid support, reactive power compensation, etc. The operating various parameters of cold storage and irrigation system are given to SM for power reference estimation. The surplus power is supplied into the utility grid for maximum profit. Finally, all the information is communicated to SM via communication links. Therefore, the information is updated all the time and it is available on the screen. 1/3 C. ,:. Inler ng - nvttr S" S .... ' Siutr% P, P." -P.oilp" Powr B."

In one embodiment, the refrigeration system includes a photovoltaic panel, a variable speed compressor, an insulated enclosure, and a thermal reservoir.

DESCRIPTION

The SM is coordinated operation multiple sources for effective power management. It is able to monitor the total system generation, individual source output power, load status, and load demand. Based on available power in the sources, the SM defines the power references for sources for effective power management in order to meet load demand. The SM system is able to exchange the power with a grid on a priority basis. The SM is adaptive to power references based on the availability of sources and critical load. Effective ancillary services are also defined by the SM system.

SM is operated on a system that may have the 'n' number of sources (Si, S2 , . . ..Sn), ESSs, and loads (critical or/and non-critical). Also, it may have a single bus or multibus structure. In Fig.1, critical loads are connected through the control switches (Lei, L 22. ,... . ) and non critical loads are connected through the control switches (Lci, Lnc2,... ). Sources and ESSs are connected to respective buses via controlled converters. The SM is connected to a conventional grid through a static transfer switch (STS) and the converters that depend on the nature of supply and the voltage level.

Power output from individual sources is controlled based on available power in the respective source, critical load demand, ESS status, and utility grid condition. The power references are estimated by SM and communicated to the distributed controller of an individual source. The distributed controller ensures tracking of power by maintaining power quality. The load curtailment is based on priorities, the critical load is defined such as cold storage, irrigation load, and local lighting load by default. The priorities can be modified by the user. The cold storage status (temperature, volume), as well as irrigation requirement (soil moisture, ambient temperature, crop period), is monitored for critical load management. In islanded/grid connected mode the SM maintains power quality. In grid connected mode, power flow with utility grid is controlled by considering grid condition, critical load demand, tariff structure, etc. Communication links are used to share information. The shared information is communicated to central controller. The data from all the sensors located at sources, ESSs, converters, switches, and meters is collected and transfer to SM for processing. Communication links are used for various purposes such as • Feedback signal- The measured data from the sensors to processing unit i.e. SM. • Control signal to converter- The control signal to the converter after processing at SM. • Control signal to switches -The control signal to switches for controlling load demand. • Communication among each SM and utility grid- For effective power management.
