Demand response (DR) can be very useful for an industrial facility, since it allows noticeable reductions in the electricity bill due to the significant value of energy demand. Although most industrial processes have stringent constraints in terms of hourly active power, DR only becomes attractive when performed with the contemporaneous use of battery energy storage systems (BESSs). When this option is used, an optimal sizing of BESSs is desirable, because the investment costs can be significant. This paper deals with the optimal sizing of a BESS installed in an industrial facility to reduce electricity costs. A four-step procedure, based on Decision Theory, was used to obtain a good solution for the sizing problem, even when facing uncertainties; in fact, we think that the sizing procedure must properly take into account the unavoidable uncertainties introduced by the cost of electricity and the load demands of industrial facilities. Three approaches provided by Decision Theory were applied, and they were based on: (1) the minimization of expected cost; (2) the regret felt by the sizing engineer; and (3) a mix of (1) and (2). The numerical applications performed on an actual industrial facility provided evidence of the effectiveness of the proposed procedure.

“…For homes in general we believe the battery bank as part of the HES is the most convenient choice given the cost and modularity provided by this ESS. Particularly relevant when it comes to ESS technology review are (see [12], [13], [14], [15], [16], [17] and [18]) all presenting important contributions to the subject.…”

“…Once the project is decided upon, there comes the need to deal with system sizing, optimization of different system components and of the system as a whole, including energy system design, optimal control of HES. By choosing the right components and the appropriate system configuration, their costs can be minimized through proper equipment sizing and load matching (see [12], [13], [14], [15], [16], [17] and [18]). The bottom line is to make the most efficient use of NCRE sources and the HEPS configuration chosen throughout the lifetime of the system.…”

Abstract:According to seismologists Chile has yet to face another big earthquake in the very near future, yet the country remains largely unprepared against massive electric power systems brake-down. The problem lies in the centralized electric power systems and the lack of adequate technologies and back-up/emergency power systems for disaster recovery. The flaws that are built into the very fabric of the presently centralized power systems were on full display in the February 27th earthquake in Chile. Nowhere it becomes more evident that hugely centralized power generation and distribution systems are extremely vulnerable and ineffective to disruptions from natural disasters, human error or other calamities. The large power networks that once proved very efficient and secure, are now at the center of discussion fueling the need for decentralization and the rapid growth of distributed generation (DG). Highly decentralized, diversified and DG-oriented energy matrix is notoriously much better suited to withstand these disasters. In centralized electric power grids, servicing large metropolitan areas, albeit with some but limited differentiation in service, can only be on or off, so either everyone gets power or no one does. This makes recovering power service in an emergency situation a much more difficult task. On the other hand, decentralized power systems (DPS) reduce the obstacles to disaster preparation and recovery by allowing the focus to shift first to critical infrastructure and then to flow outward to less integrated outlets. A DG-based model for a smart micro-grid based on hybrid electric power systems (HEPS) using both renewable energy technologies (RET) and conventional power generation units is presented. The hybrid energy system may be portable or fixed in one place, highly reliable, easy to assemble, modular, flexible and cost-effective solution, that is ready-to-run and go to where it is needed to supply power in natural disaster.

A small power, mixed wind and PV array generation system (WPVGS) working in off-grid regime, that comprises a dual input hybrid buck LC converter (HBLC) with high ratio of the input/ output voltage, a battery bank and a corresponding energy management control is presented in this paper. Analytical description, digital simulation and experimental results are given for the HBLC. The control technique uses the maximum power point (MPP) tracking or power regulation (PR) modes for the input renewable energy sources, taking into account the battery state of charge (SOC). Digital simulations of the WPVGS show the behaviour of the system in three possible operating modes.Keywords -multi-input DC-DC power converter, highgain DC-DC converter, hybrid energy conversion system, stand-alone power generation system, maximum power point tracking.
