Description

A SYSTEM AND METHOD FOR ELECTRICAL LOAD MANAGEMENTFIELD OF INVENTION

[0001] The present invention generally relates to the field of renewable energy systems. More specifically, the present invention is related to a system and method for electrical load management.BACKGROUND OF THE INVENTION

[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.

[0003] The increasing global demand for renewable energy sources has led to the widespread adoption of solar power systems. However, one of the primary challenges of solar power system is its intermittent nature, which can lead to insufficient generation of solar energy, thereby impacting the reliability of solar energy as a consistent energy source. To address these intermittencies, the existing prior arts often rely on energy storage devices, such as big batteries, to store excess energy during high solar energy production and release it during low solar energy production. While these systems provide a degree of stability, they typically require large-capacity energy storage systems, which come with significant upfront costs and complex integration requirements. Moreover, traditional grid-tied power conversion devices are designed to operate in synchronization with the grid and often include anti-islanding protection mechanisms, which prevent the energy conversion device from supplying power when the grid is down.

[0004] The growing adoption of solar energy has also been hindered by additional challenges, such as government-imposed network charges on locally produced solar electricity. These network charges further exacerbate the cost burden for consumers, making it less economically viable for residential, commercial, and industrial users to adopt solar energy on a large scale. Additionally, when relying on grid-tied systems, users are typically bound by thelimitations of the grid infrastructure, often making it difficult to harness solar energy independently during grid outages or in off-grid locations.

[0005] Existing solutions that aim to mitigate these challenges involve costly modifications to grid-tied inverters and the implementation of high-capacity energy storage devices. However, these systems often fail to fully leverage the existing infrastructure and require substantial investments for integration. In particular, the requirement to bypass antiislanding protection mechanisms, which prevent grid-tied power conversion devices from operating in isolation, presents a significant challenge to maintaining the reliability and efficiency of solar power systems when the grid is unavailable. Furthermore, the existing solutions do not optimize energy utilization.

[0006] Therefore, there is a need for a system and method for electrical load management to address the above-mentioned challenge.OBJECTS OF THE INVENTION

[0044] The detailed description includes specific details for the purpose of providing a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without these specific details.

[0045] Fig 1. illustrates a block diagram of a traditional electrical management system 100, in accordance with prior art. traditional electrical management system 100 may include a solar power system 102 as the main source of power generation. The solar power system 102 may be a photovoltaic (PV) array. The PV array captures solar energy and converts it into Direct Current (DC) electricity. This electricity is processed by an off-grid energy conversion device 104, which transforms DC power into alternating current (AC) power suitable for running connected electrical loads 106. The system may include an energy storage unit 108 to manage fluctuations in solar energy generation. The energy storage unit 108 stores surplus power generated by the PV array during periods of high solar energy output and low load demand. This stored energy is discharged during periods of insufficient solar energy generation, such as nighttime or cloudy conditions, to maintain a continuous power supply to the electrical loads 106.

[0046] The traditional systems for integrating solar power systems with existing electrical grids face significant challenges, including the need for high-capacity energy storage, costly infrastructure upgrades, and reliance on grid synchronization for stable operation. These limitations result in inefficiencies, increased costs, and limited adoption of renewable energy solutions. Additionally, anti -islanding protection mechanisms in grid-tied power conversion device restrict the independent operation of solar power systems during grid outages, further reducing their reliability.

[0047] While effective for standalone operations, the traditional electrical management system has notable limitations due to its lack of integration with the utility grid. This isolation restricts the system's ability to dynamically balance energy demands during periods of fluctuating solar energy generation or varying load requirements. Without grid connectivity, the system is unable to leverage external power when solar energy or stored energy in the energy storage unit is insufficient, resulting in potential power shortages. Additionally, during times of excess solar energy generation, the surplus energy cannot be redirected to the grid, leading to wasted resources. This inability to optimize energy flow between the PV array, energy storage unit, and potential grid support makes the system less adaptable, less efficient, and economically suboptimal for addressing real-time energy needs and transient conditions.

[0048] The present invention addresses these challenges by introducing an electrical load management system that optimizes energy flow among the solar power system, energy storage unit, and the electrical grid. By employing a primary energy conversion device and the energy storage unit to generate stable AC voltage, the electrical load management system bypasses the anti-islanding protection, enabling the solar power system to operate independently of the electrical grid. Furthermore, the system comprises a controller dynamically prioritizes solar energy usage while minimizing grid dependency. Further the system comprises a switching unit that ensures efficient energy distribution among the solar power system, the energy storage unit and the electrical grid.

[0049] Fig. 2 illustrates a block diagram of an electrical management system 200, in accordance with an embodiment of the present invention. The electrical management system 200 may include a solar power system 202. The solar power system 202 captures solar energy and converts the solar energy to electrical power. The electrical power generated by the solar power system 202 may be utilized for supplying the solar energy directly to the connected electrical loads 204 or being stored in an energy storage unit 206, such as an electrochemicalbattery, for subsequent use. The energy storage unit 206 may act as a buffer, ensuring a stable electrical power supply during periods when solar energy generation is insufficient or when there is a sudden increase in solar energy demand. In an aspect photovoltaic (PV) array may be used here as the solar power system 200.

[0050] The electrical management system 200 may include a primary energy conversion device 208 which is linked to the energy storage unit 206. The primary energy conversion device 208 may include a Switched Mode Power Supply (SMPS) with DC voltage control. The primary energy conversion device 208 converts the stored direct current (DC) voltage from the energy storage unit 206 into a stable alternating current (AC) voltage. The AC voltage output is precisely regulated to mimic electrical grid characteristics, including the standard voltage and frequency such as 220V / 415V and 50 Hz. The stable AC voltage is then delivered to a secondary energy conversion device 210 which is tied to an electrical grid 212. By providing the stable AC voltage, the primary energy conversion device 208 effectively bypasses an antiislanding protection mechanism of the secondary energy conversion device 210, enabling uninterrupted system operation even in the absence of electrical grid power.

[0051] The anti -islanding protection mechanism in the secondary energy conversion device 210 is designed to prevent the secondary energy conversion device 210 from continuing to supply power to the electrical grid 212 when the electrical grid 212 is offline. This is achieved by detecting the absence of a stable electrical grid signal. The secondary energy conversion device 210 periodically injects voltage or frequency disturbances into the grid connection. When the electrical grid 212 is active, these disturbances are absorbed and nullified by the grid's robust voltage reference. However, when the electrical grid 212 is offline, there is no reference voltage to stabilize these disturbances. As a result, the secondary energy conversion device 210 detects the drifting voltage or frequency and shuts down to avoid potential risks, such as back feeding energy into the electrical grid 212. Such feature is essential for safety during grid outages, but it also disables ability of the secondary energy conversion device 210 to supply power locally.

[0052] The bypassing of anti- islanding protection mechanism within the electrical load management 200 stimulates the presence of the electrical grid 212 by generating the stable AC voltage using the primary energy conversion device 208. The generated voltage matches the standard characteristics of the electrical grid 212, such as frequency and amplitude, and is fed into the grid port of the secondary energy conversion device 210. By providing the stable ACvoltage, the bypass mechanism effectively "fools" the anti-islanding protection system into perceiving that the electrical grid 212 is active. This enables the secondary energy conversion device 210 to remain operational and supply power from the solar power system 202 and energy storage unit 206 to the electrical loads 204, even in the absence of the actual electrical grid 212.

[0053] The power supply from the electrical grid 202 serves as a backup source, providing energy to the electrical loads 204 when solar power system 202 and energy storage unit 206 cannot meet the load requirements. This ensures an uninterrupted power supply, particularly during periods of high demand or prolonged solar energy unavailability.

[0054] The electrical management system 200 may further include a switching unit 214. The switching unit 214 dynamically controls the distribution of energy among the solar power system 202, the energy storage unit 206, and the electrical grid 212. The switching unit 214 ensures that the most economical and sustainable energy source is prioritized. When solar energy is sufficient, it directly powers the electrical loads 214, with any surplus energy stored in the energy storage unit 206. If solar energy falls short, the energy storage unit 206 compensates by discharging its stored energy. Only when neither solar energy nor energy in the energy storage unit is adequate, the switching unit 214 connects the energy from the electrical grid 212 to the electrical loads 204. Such mechanism eliminates the need for synchronization between solar energy and energy from electrical grid 212, ensuring independent and efficient energy management. In one implementation the switching unit 214 is made of Silicon-Controlled Rectifier (SCR).

[0055] The electrical management system 200 may further include a rectifier 216 connected to the grid port of the secondary energy conversion device 210. The rectifier 216 directs the flow of excess energy generated by the secondary energy conversion device 212 into the energy storage unit 208 and prevent energy backflow into the secondary energy conversion device 210. During scenarios where, solar energy generation exceeds the immediate load demand, the rectifier 216 channels the excess energy to recharge the energy storage unit 206. Conversely, during grid-related transients, the rectifier 216 ensures that energy from the electrical grid 212 or other sources does not backflow into the secondary energy conversion device 210, maintaining the system's stability and efficiency.

[0056] Furthermore, the electrical management system 200 may include a controller 218. The controller 218 act as system's intelligence hub, coordinating the operation of all components. The controller 218 continuously monitors energy production, storage levels, and load requirements. Based on this real-time data, the controller 218 dynamically adjusts the energy flow. It prioritizes solar energy usage, followed by energy usage from the energy storage unit 206, and then energy from the electrical grid 212. The controller 218 also manages transient conditions, such as sudden increases in load or drops in solar generation. For instance, if excess solar energy is generated, the controller 218 redirects it to the energy storage unit 206 through the rectifier 216, preventing backflow and energy wastage. Similarly, during power shortages, it ensures that the electrical grid 212 is engaged only when absolutely necessary, minimizing dependency of the electrical grid 212.

[0057] Fig. 3 illustrates a graph 300 depicting variation of the solar power system throughout the day, in accordance with an embodiment of the present invention. The figure provides a graphical representation of the variation in power output from a solar power system 202 over time. The X-axis corresponds to time, measured in hours, while the Y-axis represents power output in watts (W). Specific data points are captured at 8:00 AM and 10:00 AM to illustrate the system's operation and its ability to dynamically balance energy supply across various sources to meet load demands. At 8:00 AM, the power generated by the solar power system 202 is recorded as 300 W, which is insufficient to meet the total load demand of 800 W. The system compensates for this shortfall through the coordinated operation of its components. A portion of the load, specifically one device requiring 400 W, is powered using energy stored in the energy storage unit 206, which discharges an additional 100W to supplement the available solar energy. The second device, also requiring 400W, is powered by the electrical grid 212. This dynamic distribution of power, controlled by the controller 218 ensures that the electrical loads 204 remain fully operational without interruption, even when solar energy generation is limited.

[0058] The solar power system 200, at 10.00 am, produces more solar energy due to the increase in solar radiance. The solar energy generated at this time may either supply power directly to the connected electrical loads 204, may recharge the energy storage unit 206, or may perform both functions simultaneously, depending on the state of charge of the energy storage unit 206 and the real-time power demands. If output of the solar power system 202 becomes adequate to fully meet the load requirements, the system will prioritize solar energy to powerthe electrical loads 204, thereby minimizing or completely eliminating the dependency on electrical grid power. Furthermore, the system employs an intelligent energy allocation mechanism to ensure that the solar power supply operates independently of the electrical grid 212, maintaining electrical isolation. This ensures the solar energy and electrical grid power are never getting mixed. So, the solar power system 202 becomes independent of the electrical grid 212.

[0059] Fig. 4 illustrates a block diagram depicting the schematic algorithm of controller 218, in accordance with an embodiment of the present invention. The process begins with the generation of solar energy. The controller 218 checks the availability of solar energy and begins powering the connected electrical loads 204. In an implementation, if solar energy is sufficient to meet the load demand, the switching unit 214 switches the source of energy from electrical grid 212 to solar power system 202. The switching unit 214 can be an ACB (Automatic Circuit Breaker). The system ensures that the energy storage unit 206 power is equal to zero, as the secondary energy conversion device alone powers the electrical loads 204. This ensures that the electrical loads 204 are powered by the solar energy as the primary source. In another implementation, if solar energy is insufficient to meet load demand, the system coordinates between the secondary energy conversion device 210 and the SMPS (Switched Mode Power Supply) to manage the energy flow. The controller 218 increases the SMPS current reference by x, calculated as: x = p I Energy storage unit voltageHere, p is the smallest permissible power increment in the secondary energy conversion device 210, and the current increase creates a delta current loop in the primary energy conversion device 208 and SMPS. Simultaneously, the controller 218 raises the power limit of the secondary energy conversion device by p and measures the actual power increase, denoted as pTrue. If pTrue < p, the SMPS current limit is reduced by y, calculated as: y=p-pTrue I Energy storage unit voltageIf pTrue= p then the adjustments are repeated iteratively until pTrue < p, ensuring that the power flow is stabilized between the secondary energy conversion device 210 and the SMPS.

[0060] In another implementation, if the secondary energy conversion device 210 current surpasses the SMPS current, the system disables the SMPS by setting its current reference tozero. The power limit of the secondary energy conversion device 210 is set to its maximum possible value, ensuring the secondary energy conversion device 210 operates at full capacity to meet load demand.

[0061] Further, in another implementation, if solar energy becomes insufficient due to a reduction in solar generation or an increase in load demand, the system dynamically adjusts to maintain a stable power supply. The energy storage unit 206 temporarily supplies the additional power to the electrical loads 204. If discharging of energy storage unit 206 exceeds the smallest permissible power level change, delta, the controller 218 switches the ACB to engage the electrical grid 212. This ensures that the grid powers any load exceeding support capacity of the energy storage unit 206, preventing excessive energy storage unit discharge.

[0062] Furthermore, in another implementation, if solar energy suddenly becomes surplus, either due to increased generation or decreased load demand, the controller 218 ensures efficient utilization of the excess energy. The system operates by increasing the SMPS current reference and secondary energy conversion device 210 power limits to manage the surplus. Once the surplus exceeds delta, the ACB is activated, enabling solar energy and energy power from the energy storage unit 206 to handle the extra load. This reduces grid consumption by delta.

[0063] The electrical load management system offers significant advantages in optimizing energy utilization and ensuring reliable power delivery. By prioritizing solar energy and seamlessly integrating it with energy storage unit and electrical grid power, the system reduces dependency on the electrical grid and promotes renewable energy adoption. Th innovative bypass mechanism eliminates the need for electrical grid synchronization, allowing uninterrupted operation of electrical grid-tied energy conversion device, even during outages. The system effectively addresses power fluctuations with a dynamic energy flow control strategy, ensuring stable power supply to loads while minimizing energy storage unit wear and prolonging its lifespan. Additionally, the inclusion of a rectifier prevents energy backflow during transients, enhancing system reliability. The cost-effective design minimizes the need for large energy storage solutions, lowering installation and operational costs while facilitating compatibility with existing grid infrastructure. This comprehensive solution supports sustainable energy management for residential, commercial, and industrial applications.
