DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

I. Hybrid Modular Power System 2; General Description

[0015] The embodiments discussed herein are merely illustrative of specific manners in which to make and use the invention and are not to be interpreted as limiting the scope of the instant invention.

[0016] FIG. 1 shows a hybrid modular power system 2 embodying an aspect of the present invention. Without limitation, a housing or container 4 is shown for a multi-user or multi-tenant application with four individual power modules 7, each enclosed within a respective cabinet 6. The housing 4 and the hybrid modular power system 2 are scalable as needed for various applications and users. For example, individual tenants can specify custom power module configurations, capacities, telecommunications, energy modes, microprocessor-based operating systems, etc. Relatively large-scale housings can comprise standard-dimension shipping containers, which are compatible with intermodal transportation, including: container ships; railcars, over-the-road trucks and trailers, etc. Housings with smaller footprints can also accommodate the power module 2 in scaled-down applications.

[0017] FIG. 1 shows the system 2 with photovoltaic panel array 14 and wind turbine 24 renewable energy source subsystems deployed. The photovoltaic panel array 14 generally comprises an array of individual photovoltaic panels 16, which optionally can be hingedly connected along fold lines 18, whereby the array 14 can be compactly folded for transport, compact storage, etc. The panel array 14 is shown in a horizontal planar orientation, which would optimize electrical output in locations near the equator. Optionally, the array 14 can be tilted to sloping orientations for optimizing solar radiation reception and corresponding electrical current output.

[0018] The wind turbine energy source subsystem 24 includes a mast 26 with a mast mount 28 attached to the housing 4. The mast mount 28 accommodates raising and lowering the mast 26, which could be accomplished with a hoist mechanism similar to that shown in U.S. patent Publication Ser. No. 16/460,360, which is incorporated herein by reference. The mast 26 can comprise multiple sections, e.g., 2 are shown comprising proximate and distal sections 30a,b interconnected by a mast section hinge 32. For storage and transport, the mast 26 can be folded double and laid atop the housing 4.

[0019] A wind turbine 34 is mounted on top of the mast 26 and is configured for pivoting to an upwind orientation for optimizing electrical output. Wind turbine 34 output is also a function of elevation. Multiple mast sections 30 can be provided for positioning the wind turbine 34 at an optimal elevation above grade. Moreover, the housing 4 can be installed on top of a base structure, such as another hybrid modular power system 2. In other words, the housings 4 are configured for stacking. The mast 26 is also configured for mounting antennae for the telecommunications component 12, as shown in U.S. patent Publication Ser. No. 16/460,360.

II. Housing 4

[0020] FIGS. 2 and 3 show exploded views of the housing 4, which includes a housing frame 36, a roof 38 and a floor 40. A side door 42 provides access to the housing interior, which can contain multiple (e.g., four are shown) cabinets 6 for accommodating equipment specific to the individual requirements of multiple tenants. The individual power modules 7 can be accessed through respective power module doors 43. The doors 43 can be equipped with keyed locks, card-based radio frequency identification (RFI) locks, combination locks and other security measures to limit access to the individual power modules 7. For example, in a multi-tenant facility, each tenant's access can be restricted to its power module 7 and other tenant-specific components on an as-needed basis.

[0021] A power conversion cabinet 46 is also located in the housing interior and contains electrical components for converting and transforming the power inputs (e.g., one or more of solar, wind, battery, genset and grid sources) to electrical power in forms required by particular user and customer applications. For example, customers' electrical power requirements can vary considerably, including power levels, AC or DC, two-phase or three-phase AC, voltage, peak vs. non-peak fluctuations, constant or intermittent load demands, varying power usage cycles, etc. The control subsystem 8 can be pre-programmed to manage, balance and adjust the output power and form to accommodate such user needs with the power conversion components in the cabinet 46. A genset 48 is installed on top of a fuel tank 50 (FIG. 4) in the interior of the housing 4. The hybrid modular power system can include multiple gensets for producing AC/DC current at various voltages to accommodate different electrical load requirements. The housing 4 interior can be partitioned with internal wall panels, such as the genset panel 52. Additional panels, such as external vented genset panel 53, can be installed as needed.

III. System 2 Schematics (FIGS. 5-7)

[0022] As shown in FIG. 5, the system 2 includes a smart control subsystem 8 with a microprocessor or programmable logic controller (PLC) 10 and a telecommunications (telecom) component 12. The telecom component 12 can accommodate wireless telecommunications via satellites and direct transmission. The system 2, via the telecom component 12, can also accommodate hardwired (landline) service. Electrical sources providing inputs to the system 2 include the grid 54, an AC genset 56, a DC genset 58, renewable energy inputs (e.g., solar and wind, collectively 60) and a battery array 62. Without limitation, the batteries can be lithium ion for performance, recharging and service life characteristics. FIG. 5 schematically shows examples of inputs and outputs to the system 2. Without limitation, AC and DC input current is received at 64, 66, respectively. AC current is output to loads at 65. Optionally, the control system 8 can convert AC to DC, and vice versa to dynamically accommodate and balance available inputs with load demands, as indicated by the directional current flow arrows 67. The control subsystem 8 can include electrical circuit breakers 68 and a surge protection device (SPD) 72 with suitable ratings for accommodating various loads 70, the battery array 62 and other electrical connections for overload protection of the system 2 components.

[0023] FIG. 6 shows the AC genset source 56 and connections to the system 2. FIG. 7 shows connections to the system 2 for the renewable solar and wind electrical power sources 14 and 24, respectively.

IV. Hybrid Modular Power System 2 Method and Operation

[0024] In operation, the system 2 can be configured for transportation by truck, rail, marine vessel or air. Remote, off-grid locations can thus be served by the system 2. Moreover, the system 2 can be relocated as necessary. Examples of relatively permanent installations include telecommunications equipment sites. Relatively temporary installations include construction sites. Moreover, rapid-response electrical power needs can be accommodated by transporting the system 2, e.g., for responding to crises and natural disasters.

[0025] One or more compartments 6 can accommodate personnel and equipment specific for procedures and activities as required by the tenants. For example, with proper equipment medical, dental and veterinary clinical procedures can be accommodated in remote, off-grid locations and elsewhere.

V. Alternative Embodiment Hybrid Modular Power System 102

[0026] FIG. 8 shows a telecommunications-enabled hybrid modular power system 102 comprising a modified or alternative embodiment of the present invention. A mast 104 includes a distal end 106 mounting a parabolic reflector microwave antenna 108, which can be oriented for focused, linear transmission and reception, e.g., signal transmission to and from another microwave antenna. An antenna array 110 comprising multiple individual antenna units 112 is mounted below the parabolic reflector antenna 108. The antenna units 112 are mounted in radially-spaced relation around the mast 104.

[0027] The hybrid modular power systems 2 and 102 can be configured with additional combinations of wind turbines and antennae to accommodate the requirements of the hybrid power module tenants and users. For example, a wind turbine can be mounted on the mast distal end, with antennae located below.

[0028] It is to be understood that while certain embodiments and/or aspects of the invention have been shown and described, the invention is not limited thereto and encompasses various other embodiments and aspects.
