Operating stationary fuel cells on power system and microgrids

The integration of stationary fuel cells for dispersed power generation is a challenge for utilities and service provider in the next few years. Local distribution companies have to assess the impact of distributed generation on power system planning, operation, protection and tariff. Service providers have the opportunity to power microgrids by fuel cells. Rating of fuel cells and limitations of connectable power are discussed. The impact on protection scheme of power systems and microgrids are described. Remedial measures are proposed to ensure safety and selectivity.
