Assessment of the production costs curve in micro-grids: a comparative analysis
In micro-grids, due to their small scale, there is commonly only one power supplier. A competitive wholesale market hardly exists so the question about how to consider market issues for small producers within micro-grids arises. On the other hand, the specific features of micro-grids where load and generated power hardly find a balance, require that customers take part to regulation issues, maybe using demand response programs. In this paper, price responsive policies and its programs are discussed to answer this question. A case study of a micro-grid with one microturbine and two photovoltaic generators in Italy is analyzed to assess the overall production cost in order to build a price re…
Demand Response Pricing Strategies for Islanded Microgrids
In this paper, Time of Use and Critical Peak Pricing policies are designed and their effects on optimized operation is evaluated. For this purpose, an optimal operation algorithm is employed and the relevant production costs are derived. As far as the Time of Use policy is concerned, such costs are observed to be different in two time intervals of the day, due to the loads changing effect and the production of renewable energy. Whereas in the Critical Peak Pricing Policy, a peak time interval is identified to set up different pricing rates. The optimization algorithm used to carry out the work described above minimizes the microgrid's energy losses, the production costs and the Green House …
