X-FLEX project will design, develop and demonstrate a set of tools in order to integrate the emerging decentralized ecosystem of RES and flexibility systems into the existing European energy system, in an efficient and cost-effective manner, in order to create more stable, secure and sustainable smart grid, with special attention to extreme weather conditions. The project will address all the actors of the smart grid value chain, from Distribution system operators (DSOs) to final consumers, including microgrid operators and utilities, considering flexibility in both on the generation and on the demand side, on an individual or aggregated level.

X-FLEX will develop 4 complementary products:

• SERVIFLEX tool is the tool for flexibility managers to take advantage of the value of energy storage along with other demand flexibility resources.

• GRIDFLEX tool is the tool for grid and microgrid operators in order to prevent congestion (voltage and current issues) and power quality problems.

• MARKETFLEX tool enables final consumers and prosumers (generation, DR, flexibility providers) to access the market individually, through an aggregator.

• X-FLEX platform integrates all the X-FLEX solutions in order to provide services for all the energy actors and ensure more secure, stable and clean energy supply.

These solutions will be tested in real conditions in 4 pilot sites in 3 EU Member states: Bulgaria, Slovenia and Greece.
