Dear Colleagues,

Currently, we are driving a revolution by pushing new technologies, such as renewable energy systems (RES), demand side management (DSM) and demand response into our energy system in order to make them more sustainable, smarter and integrated becoming so a smart multi energy system (MES). RES and sustainable generation technologies are often connected to electricity distribution networks in the form of distributed generation (DG), at the low voltage (LV) or medium voltage (MV) level and can modify the operation of electricity network. The direction of power flows in the MV lines and even in high voltage/medium voltage (HV/MV) transformers can be reversed, voltage profiles are modified, fault management is affected. Moreover, DSOs (distribution system operators) are also enhancing the ICT (information communication technologies) layer used to monitor and control distribution networks. Furthermore, ICT and MES offer valid options to foster novel services for smart energy management. For example, they can foster events of DR and DSM by integrating buildings equipped with heat pumps, combined heat power or HVAC (heating, ventilation and air conditioning) systems. For all these reasons, distribution networks need to become smart and new control strategies, algorithms and technologies need to be tested and validated before their implementation and installation in real systems. However, this transition cannot be left to chance thus, specific tools to evaluate resource availability, uncertainty of RES and smart energy policies are required: i) to understand their impact on power grids; ii) to perform load balancing; iii) to perform storage planning and management; iv) to perform demand-side management at different scales, from single user up to district or city; v) to provide generation profiles to electricity markets (e.g. day-ahead or intra-day market).

In this Special Issue, we are particularly interested in innovative solutions for planning, analysis and optimization of smart multi energy systems in order to foster this radical change.

Topics of interest include, but are not limited to, the following:

• Simulation tools for RES integration in distribution system;
• Agent based model for simulating the planning and operational phase of smart multi energy system;
• Models for synthetic data generation;
• Planning the electric vehicle charging station position with respect to grid operation;
• Modelling and simulation tools for evaluating the electricity demand flexibility;
• Novel solutions for intelligent energy control in buildings for smart city applications;
• Heat electrification to increase renewable generation share;
• Real-time co-simulation of multivector energy systems;
• Cybersecurity and data privacy issues in electric vehicle smart charging;
• Flexibility provision via smart multi energy services in the energy grid;
• Impacts of multi energy system integration on the dynamics of power systems;
• GIS tools for energy planning and management;
