This workshop is motivated by the need for Europe to transition its energy markets (generation, distribution and consumption) into smart energy systems that support bi-directional flows of revenue, energy and information, the increased penetration of DER, self-consumption of on-site generation, and the optimization of energy flows in a safe, reliable, secure, and affordable way. It brings together industrials, ICT and cyber security experts, energy suppliers / retailers, distribution grid operators (e.g. DSO, DNO), scientists, business analysts, and power engineers to share and exchange their experiences and ideas towards progressing state-of-the-art in residential / commercial premise energy consumption optimization that facilitates aggregated flexibility trading and leads to prosumer-oriented smart European energy communities. WORKSHOP TOPICS·         Enhancing LV-grid reliability, cyber-secure performance, and resilience·         Controllable load/self-optimization in EU “districts” and “neighborhoods”·         Interconnection of various devices (hardware) & agents (software), from the value chain covering smart meter to the national networks. ·         Models of European LV-grid topologies, markets, and regulations·         Emerging technologies (i.e. Link-Boxes) for LV substation performance optimization, automation, and enhanced peak load profile monitoring·         Self-consumption and peak shaving with the presence of grid constraints·         Optimization algorithms, protocols/semantics, and prediction forecasting·         Future Smart Energy Market model (example: USEF framework)·         Substation Automation for peak load reduction and peak shifting·         Use of local flexibility and web services to offset grid reinforcements·         Energy consumption and energy management at HAN level·         District and community engagement of RES / DER
