Abstract

In this paper, we propose an energy management system with hybrid solar and wind renewable energy system (RES) with Multilevel inverter to give a lossless power to load. This system continuously receives the battery storage and power consumption after it checks the these value with default value if power consumption is exceeds default value means it turn off  the loads. We are assigns the priority to the loads in order to overcome the user inconvenient. To increase PV module output MPPT is used. The existing system uses only boost converter, in our paper boost converter is combined with buck converter used because the PV module can produce high voltage  than DC-bus voltage. Buck converter used to step down purpose. In this  system  on-line configuration check and buck-boost mode transition will be presented. Experimental results measured from three-string MPPTs with EMS the maximum power level of 10 kW are used to verify the analysis and discussion with hybrid cascaded multilevel inverter.DOI:http://dx.doi.org/10.11591/ijece.v4i1.4529

Abstract

This paper presents the Solar (photo voltaic) power Plant and Windmill plant with DC Smart Grid connected with an DC Fuel Charging Station For Electric Vehicle (EV), Plug in Hybrid Electric Vehicle (PHEV) and converted to AC load for Consumer single or Three phase ac load by means of Hybrid Multilevel Inverter (MLI). Solar Energy which store energy in lithium-ion battery and connected to Smart Grid .Wind Energy which get stored in Lithium-ion battery that Fixed DC Voltage connected with DC Smart Grid. Smart Grid which are Connected with DC Fuel Charging Station in Ring Topology with a certain distance for charging of Electric Vehicle (EV) and Plug-in Hybrid Electric Vehicle with On-Board (Integrated) Charger for faster charging of EV. In Power demand for Consumer the DC load from smart grid converted into an ac load by Hybrid Multilevel Inverter. In Consumers Place the small wind mill and PV panel are installed that energy can be used for consumers load at peak time or power Shutdown .Other than the power shutdown or peak time in the consumers place, stored DC Energy can be fed to Smart Grid. A major development in distribution automation is deployment of smart meters as a gateway between the utility and customer. With such capabilities the smart meter becomes not only a point of measurement of consumed kWh but also a controller capable of bidirectional communications with both the customer and utility.DOI: http://dx.doi.org/10.11591/ijpeds.v3i3.3884
