A DER based voltage control strategy for microgrids

摘要: Recently, the ability of microgrids (μgs) to allow a deeper penetration Distributed Energy Resources (DERs) in Distribution Networks (DNs) has facilitated their widely spread deployment. Because variability associated with loads and intrinsic intermittent nature renewable energy resources, development implementation effective voltage control strategies is essential reliably serve loads, particular when working islanded from main grid. To face this problem, we propose dispersed approach capable maintain levels within operational limits by means DERs reactive active power support. We implement an optimization framework prove robustness proposed methodology. illustrate effectiveness methodology set representative studies testing simulation performed, proving absence any opportunity cost involved action.
