A convenient demand response layout for energy efficient residential prosumers

Abstract

Demand response (DR) is a high priority smart grid technology yet, efficient implementation of the same at the circuit level is often overlooked. Technologies like DR is vital to the improvement, stability and reduction of congestion in the grid. At the distribution side, addition of photovoltaic (PV) systems with appropriate metering has made consumers to prosumers. Prosumers contribute to the grid supply and often meeting increased demand. PV installation has made surplus grid power available. Power from PV is an environment friendly approach, in-order to yield its maximum benefit, it should be appropriately connected with advanced metering infrastructure (AMI). Further, AMI enables other technologies like real time pricing (RTP), DR and demand side management (DSM). Pilot projects put forward by Government of India (GOI) has already deployed smart meters, transforming existing conventional meters into AMI. Hence, functional benefits of AMI are to be studied to its full usage potential. DR and RTP are more focused on consumer behaviour and involvement whereas, DSM is under the control of utility. Hence, novel layouts for energy efficient prosumers with net-metering, gross-metering, hybrid loads and renewable PV integration are analysed. Consumer feasibility of DR without compromising, basic needs of power availability and comfort is focused. Inference is made from both metering infrastructures, tariff schemes and its application in Puducherry locality of India.

A hybrid approach for PV based grid tied intelligent controlled water pump system

“…[4][5][6] The researchers concentrated on incorporating a water pump system powered by autonomous PV panels into the grid to solve this challenge. 7 Bidirectional power transfer control is described in the literature for IM-driven irrigation solar pumps connected to the grid. 8 Will also look at water pump system driven by solar panels integrated into the grid and PMBLDC (Brushless Permanent Magnet Motor) in Reference 9.…”
