Nowadays, wind energy has become a very viable alternative solution to provide electrical energy. The development of wind energy is especially relevant for the case of isolated island in the south central provinces of Vietnam, where there is great potential for wind energy. For these isolated systems, the co-generation of diesel generators and wind turbines is a common configuration, but also poses...
In this paper, a demand elasticity model is developed and tested for the dispatch of microgrids. The price obtained from dispatching the network in a base-case scenario is used as input to a demand elasticity model; this demand model is then used to determine the price-responsive demand for the next iteration, assuming that the load schedule is defined a day ahead. Using this scheme, trends for demand,...
A microgrid is a collection of distributed generation assets, storage devices and electrical and/or thermal loads connected to each other. In this paper, a generic model-predictive control algorithm for microgrids is presented. The algorithm has been implemented at Bella Coola, a remote community in British Columbia, Canada. The approach comprises two parts: unit commitment to decide the optimal set...
A Knowledge Based Expert System (KBES) is proposed for the scheduling of an Energy Storage System (ESS) installed in a wind-diesel isolated power system. The program optimizes the cost of operation by determining the diesel generation and the charging/discharging cycles of the storage system from the wind and load profiles one hour ahead. The rules created aim to minimize the use of the dump load...
The energy crisis requires more generation capability, and that is why the importance of the storage technologies increases. In the liberalized energy market the energy storage activity, this way of the ldquoenergy speculationrdquo is welcome. In this paper a small scale buy-sale optimization strategy is investigated. In the Budapest Tech a model has been built in the renewable energy park. The strategy...
