Abstract |
This paper studies the impact of involving the demand side of the LV grid into the grid conditioningprocess. Heat pumps are distribution loads with a substation capacity increase in the last years, withexpectancy of growth in the coming years. Controlling the loads is the first step in the transition to smartgrids, and heat pumps are to be the first promising smart loads. They can be used for load shedding butalso for unbalance compensation purposes. When they are equipped with a back to back compressor driveand a proper control strategy, grid support can be provided to reduce the negative sequence component inthe voltage at the installation point. Two control strategies are proposed and investigated experimentallyon a SiC heat pump converter prototype. |
