Valuing the moderation options in Serbia for higher wind penetrations

The flexibility of the national energy system is limited regarding future higher penetrations of wind and therefore it needs moderation options. Different system storage (e.g pump hydro storage power plant) and demand side storage (demand response e.g. electric hot water ; plug in electric vehicle) moderation options have different economic weights and availabilities, which are predetermined by their localization. Technically optimized operation for the year 2030 on an hourly basis using the EnergyPLAN tool for the future scenarios of the Serbian energy system has been performed at higher wind penetrations up to 3, 000 MW with share of renewable energy sources above 30% on a national basis and up to 7, 000 MW on a regional basis. Moderation options have been valued based on investment costs and operation, not including the energy costs, and then sorted according to their marginal costs (1.2 - 24.6 c€/kWh) into a moderation options supply curve. Demand response, as least marginal cost moderator, should be used for the moderation of higher wind penetrations in Serbia.
