PV Hosting Capacity Analysis and Enhancement Using High Resolution Stochastic Modeling

Abstract

[...]users are provided with energy management systems (EMS) that ensure the network stability and an uninterrupted supply, all of these by controlling the charging cycles, as well as the possible interactions with the main grid when either an energy surplus or shortage take place [9]. [...]no additional indicators have been developed to study the integration of distributed energy production in a grid with limited HC. In the case of the batteries ( PB(t) ), the converter is bi-directional, so they can interact with the production, as well as with the grid, aiding in the HC process. [...]each house is supposed to have a bi-directional smart electricity meter that quantifies the energy flow to and from the grid and sends information to the home EMS (HEMS) and the SCEMS that control the power interchanged with the grid ( PGp(t) ) and establish the production curtailments ( PCurt(t) ) when needed. PV HC Enhancement Finally, the third scenario illustrates the impact of control strategies focused on the enhancement of the HC. Since this control strategy depends on the battery capacity, three situations were considered, which are 4000 Wh of storage capacity per household and no enhanced control, 6000 Wh per household and no enhancement and 4000 Wh per household with two-level control using 75% of the capacity for individual control (HEMS) ( EHCmax ), whereas keeping a 25% available for HC strategies of the whole smart community (SCEMS).
