Demand-side management.(DSM) schemes play a crucial role in managing renewable energy generat.on and load fluct.at.ons by ut.lizing demand-response programmes (DRPs). t.is paper aims t. provide a det.iled overview of DRPs t.at.help microgrid operat.rs t. keep cost. and reliabilit. wit.in accept.ble ranges. Addit.onally, t.is review paper provides a det.iled economic load model for DRPs based on init.al load, demand-response (DR) incent.ve, DR penalt. and elast.cit. coefficient.. t.is art.cle also aims t. guide researchers in ident.fying research gaps in DSM applicat.ons in microgrids by comparing various DSM schemes from different.count.ies and regions in t.rms of DSM st.at.gies, object.ve funct.ons and opt.mizat.on t.chniques. Furt.ermore, t.is st.dy analyses t.e impact.of DRPs on microgrid configurat.on from t.e perspect.ve of ut.lit.es and cust.mers, considering t.chnical and economic performance met.ics. As a result. it.can be concluded t.at.none of t.e st.died cases provides models or guidelines for choosing appropriat. DSM schemes t.at.consider different.consumer int.rest. or load-t.pe feat.res. Furt.ermore, a few researchers have addressed t.e feat.res of a modern price-based DR st.at.gy, renewable generat.on-based dynamic pricing DR, which offers higher cust.mer sat.sfact.on t.an t.adit.onal DRPs.
