The ChallengesSystem integration is the primary barrier for Microgrid’s adoption Non-StandardizedEcosystemComplex SystemsRigid StructureCurrent players rely on customized & one-off control systems, increasing the time & cost of integrationCOPYRIGHT 2019 HEILA TECHNOLOGIES INC. – ALL RIGHTS RESERVED – PRIVILEGED AND CONFIDENTIAL3
Our Approachsimplifies integration and operation of DER systems by using a building-block approachAdd/remove elements seamlesslywith a self-adaptable dispatch logicGas TurbinesUtility OperatorDiesel GeneratorsBatteriesComm NetworkWind TurbinesCentralController(Optional)Solar PanelsHomogenize disparate DERs into astandardized control frameworkControl complex systems with replicable,energy agnostic intelligent nodesLoadsCOPYRIGHT 2019 HEILA TECHNOLOGIES INC. – ALL RIGHTS RESERVED – PRIVILEGED AND CONFIDENTIAL4
