Background: The day-ahead power market is an important part of the spot market. In market, participants make short-term forecasts load and output to propose bidding curve more precisely. As energy aggregators that have regulatory resources, virtual plants (VPPs) need consider uncertainty distributed renewable when participating in transactions. Methods: This paper analyzes built optimization mo...

This paper explores the procurement of flexibility services in power system by collaboration between transmission operators (TSO) and distribution (DSO) day-ahead market (DAM). With coordination interaction among operators, existing sources levels are exploited efficiently to procure services. For motivation distributed generation (DGs) microgrids (MGs) provide services, DSO aggregates flexible...

This paper proposes a simple and practical approach to model the uncertainty of solar irradiance determines optimized day-ahead (DA) schedule electricity market. The problem formulation incorporates power output distributed photovoltaic generator (DSPVG) forecasted load demands with specified level certainty. proposed certainty levels random variables (solar demand) from their probability densi...
