Maximising Revenue for Non-firm Distributed Wind Generation with Energy Storage in an Active Management Scheme
نویسندگان
چکیده
The use of renewable generation and energy storage with actively managed curtailment schemes is investigated. A heuristic optimisation algorithm is presented that maximises the revenue available to the operator of a storage system that time-shifts curtailed generation, and trades by buying and selling power on an electricity market. The algorithm is applied to a case study of a distribution network curtailment scheme with a generic storage device. It is found that allowing a storage unit to both trade with the market, and time-shift curtailed generation generates greater revenue that operating in either mode individually. A Last-In-First-Out scheme of small wind farms in a curtailment scheme is modelled to show the effect of including storage. Finally it is noted that the role of renewable subsidies is important for the encouragement of efficient storage technologies.

This paper proposes an MPC - based (model predictive control) scheme to control active and reactive powers of DERs (distributed energy resources) in a grid - connected mode (either through a bus with its associated loads as a PCC (point of common coupling) or an MG (micro - grid)). DER may be a DG (distributed generation) or an ESS (energy storage system). In the proposed scheme, the set - poin...

متن کاملBIC based on Modified Droop Control of Hybrid AC/DC Microgrid with PV/Wind/ESS under Variable Generation and Load Conditions
The idea of a microgrid is created by utilizing more diverse ac or dc distributed generation (DG) sources along with an energy storage system (ESS) and loads. The most efficient and reliable selection of ac and dc microgrids is a hybrid ac/dc microgrid. The hybrid microgrid largely overcomes the shortcomings of standalone ac or dc microgrids. A bidirectional interlinking converter (BIC) is util...
