5. Claims 1-20 are rejected under 35 U.S.C. 102(a)(1)/(a)(2) as being anticipated by Gayles (Gayles), US publication no. 2021/0359521 A11.
As per claim 13, Gayles discloses a microgrid controller of a microgrid [figure 1], comprising: one or more memories configured to store a load stabilization algorithm [para 6, 28]; a communication interface configured to receive load information corresponding to a current load demand of a plurality of loads connected to the microgrid and output one or more control signals for controlling a plurality of energy resource systems associated with the microgrid, wherein the plurality of energy resource systems includes a non-stabilizing group of energy resource systems and a stabilizing group of energy resource systems [figure 1; para 16, 17]; and
one or more processors, coupled to the one or more memories, configured to execute the load stabilization algorithm to generate the one or more control signals based on the load information [para 6, 28], wherein executing the load stabilization algorithm comprises: generating, based on the load information, one or more first control signals to dynamically control an amount of total output power provided by the stabilizing group of energy resource systems to a power distribution network of the microgrid in order to stabilize one or more cyclic loads on the power distribution network and to maintain the non-stabilizing group of energy resource systems at a substantially constant load [para 26-29, 83-84].
Gayles teaches:
[0026] The energy storage data may include, for each of the at least one energy store, a current energy level (e.g., kilowatt-hours currently stored), total energy storage capacity (e.g., kilowatt-hours of capacity), and/or discharge/charge parameters. The current energy level may be measured by a battery meter of an energy storage. The battery meter may one or combinations of: a voltmeter, an amp-hour meter, and/or an impedance based meter. The discharge/charge parameters may indicate an amount of discharge power and an amount of charge power for the energy store(s) 105B. Alternatively, to reduce transmission bandwidth, the energy storage data may omit the discharge/charge parameters, and the at least one energy store 105B may transmit
the discharge/charge parameters when the at least one energy store 105B are first connected to the controller 105C. The at least one energy store 105B may receive requests for the energy storage data to provide the energy storage data and/or continuously provide the energy storage data to the controller 105C. The instructions may include an energy storage dispatch instructions (ESD). An ESD may comprise
an instruction to inject power to the system bus of the power system 105 or absorb power from the system bus of the power system 105. In techniques presented herein, at least one ESD may be utilized to rapidly stabilize the load, thereby stabilizing the bus frequency of the power system 105 in a time efficient manner rather than attempting to stabilize the load using the generator(s) 105A alone. The at least one energy store 105B may control the inverters and the electronic control mechanisms to control (1) quantity offload drawn by the at least one energy store 105B or (2) the
amount of AC power output produced by the at least one energy store 105B, in accordance with the ESD.
[0028] The controller 105C may include at least one memory device storing instructions; at least one processor executing the instructions from memory device to perform a set of desired operations; and a communication interface facilitating the communication between various system components. The instructions may be non-transitory computer-readable instructions for executing a control application. The communication interface of the controller 105C may enable the controller 105C to communicate with the at least one generator 105A and the at least one energy store
105B, as discussed above.
[0029] The controller 105C, while executing the control application, may receive the generator data and the energy storage data, process the generator data and the energy storage data to generate an ESD, and output the ESD to the at least one energy store 105B, so that the at least one generator 105A are protected from transient changes in load. To process the generator data and the energy storage data to
generate the ESD, the control application may include a load stabilization function and/or a state of charge (SOC) function. The control application may also include a generator set limit function and/or energy store discharge/charge limit function to generate the ESD. The load stabilization function, the SOC function, the generator set limit function, and/or the energy store discharge/charge limit function may be configured manually or may be automated. In manual configuration, the aforementioned system functions might be activated or deactivated via a user input. Alternatively, the controller 105C may automatically activate or deactivate the
aforementioned system functions based on presence or absence of systems parameters (such as no generator set minimum threshold value is available, etc.). Generally, the control application may have all of the functions activated by default. Generally, the load stabilization function may ensure system bus frequencies of the at least one generator 105A are maintained at a nominal value by causing an amount of power to be absorbed/injected by the at least one energy store 105B. The amount of power may be determined based on a difference from an instantaneous load and a
moving average of the load. Meanwhile, the SOC function may ensure the at least one energy store 105B are charged to a target SOC. The target SOC may enable the at least on energy store 105B to provide long term beneficial use to the system 100, such as having a range of operation usable by the power system 105 and/or avoid degradation ranges of the at least one energy store 105B.
