- the present invention has its main field of application in the industry for the design of electronic devices and, more particularly, within the sector of photovoltaic solar power systems.
- An object of the invention is to allow the energy source to work at its Maximum Power Point (MPP), provided that this condition is required by the users, permanently without causing any discontinuity in the voltage it supplies.
- MPP Maximum Power Point
- MPP Maximum Power Point
- Solar generators such as those comprising photovoltaic panels, are widely used today both in space power systems (stations, satellites, probes and other space vehicles) and terrestrial (buildings with renewable energy facilities, etc.), due to its independence from any electricity distribution network, with the advantageous ability to supply energy autonomously to both fixed and mobile equipment.
- thermoelectric to produce electricity with a conventional thermodynamic cycle from of a fluid heated by the sun the liabilities that take advantage of the heat of the sun without the need for intermediate mechanisms and hybrid systems that combine solar energy with the combustion of biomass or fossil fuels.
- MPP Maximum Power Point
- MPPT Maximum Power Point Tracking
- the MPPT power regulation method allows photovoltaic panels, modules or collectors to supply all available power by electronically varying its operating point.
- the benefit of carrying out the MPPT is evident compared to conventional power controllers, where the panels are connected directly to the user's charging network (for example, to charge a battery), thus forcing them to operate at their own voltage level. of the battery, which frequently does not correspond to the ideal voltage for which the photovoltaic panels give the maximum power.
- MPPT tracking can be used in conjunction with the typical mechanical control, in which the panels automatically move to optimize their pointing towards the sun.
- the typical mechanical control in which the panels automatically move to optimize their pointing towards the sun.
- the power conditioning unit that includes FR2844890 generates a control signal corresponding to the difference between the instantaneous voltage and the voltage value of the MPP that serves as a reference to said conditioning unit. The drawback is that it is not possible without affecting the continuity of the voltage supplied to the user.
- the present invention is conceived for its application in the control and conditioning of power, in general, for solar energy sources whose electrical characteristic has a single Maximum Power Point.
- MPP MPP
- the process and circuit of the invention have important advantages compared to the solution set forth in FR2844890, based on a fundamental aspect for determining said MPP and which is the number of points of the real electrical characteristic of the source, which is preferably a photovoltaic panel or a group of solar panels, necessary for calculations.
- the circuit behaves like a discrete time servo system, acting as a classic power regulator that finds its new MPP after only 2 samples, always meeting the current MPP voltage without instabilities , in the direction of the new MPP without oscillations.
- MPP Maximum Power Point
- VMPP voltage and current coordinates
- IMPP IMPP
- This procedure delivers to the power conditioning unit, continuously or in sampling mode, a corresponding reference signal with the current value of the voltage VMP P , that is, the reference voltage to the input of the power conditioning unit is strictly proportional or equal to the instantaneous value of voltage at the Maximum Power Point (MPP).
- MPP Maximum Power Point
- the solar generator preferably comprises a photovoltaic panel or a grouping of such panels, or, it is an equivalent energy source, whose definition of the electrical characteristic of voltage as a function of the current v (i) is expressed, linking the coordinates of the working point in certain operating conditions, such as temperature, aging and lighting level in the solar panel, according to the following relationship developed by Tada and Carter in the eighties of the last century:
- n is defined as the number of photovoltaic cells in series in each of the m cell columns of the panel.
- A is the so-called form factor of the characteristic and kT / q is a coefficient that depends on the temperature and the material of the cell. Also involved in this equation (2.1) are the respective values of the short-circuit current i S c and the current in the dark R of a photovoltaic cell for given working conditions.
- the graphic method consists in finding the intersection of two curves or functions f1 and f2, which follow the analytical expressions:
- the accumulated measurement data will periodically allow the microprocessor (for example, every 100 MPP changes) to know the real darkness current without this having an effect on the voltage imposed on the solar panel.
- obtaining the short-circuit current isc and the constant "a" in the current working conditions implies finding the solution to a system of equations with two unknowns, which It can be solved by means of a graphic method and an iterative calculation algorithm, such as the aforementioned Newton-Raphson method, from the initial value of the current in darkness i R.
- the first point M1 (v1, i1) is the current operating point. It is characterized by its voltage v1 that is always at the value of the preceding MPP, the "old" MPP, but with a current that has changed, since it is not that of the new MPP or that of the old MPP.
- the measurement of the difference between the current values allows to know where the new MPP is at the same time that it indicates an estimate of its distance. If the difference is positive, the voltage of the new MPP is also greater than that of the old MPP; while if it is negative, it will have a lower voltage.
- the control procedure changes the working point of the solar panel by imposing a positive step (if the difference ⁇ 1 - i M pp "old” is positive) or negative (if the difference ⁇ 1 - ⁇ M pp "old” is negative) to the reference of the power regulator.
- the amplitude of this step is proportional, with a constant k v selected by the user, to the amplitude of the difference of said current values.
- the second point M2 (v2, i2) is necessary to find the coordinates of the new MPP.
- the third point M3 (v3, i3) is calculated accordingly by the processor, its coordinates being those of the midpoint of the M1 M2 segment.
- the algorithm uses the property that this segment is parallel to the tangent at the point of the characteristic that has the same voltage as the point M3. It can be written:
- na -p (my sc)
- Another aspect of the invention is a control circuit of the Maximum Power Point for solar energy sources, whose electrical characteristic has a single MPP for working conditions in which the solar source operates according to each moment, comprising:
- a power conditioning unit connected between the solar source and a user load network, through a power cell, to regulate the output voltage of said source and provide an optimal voltage to the user's load network, with a maximum performance.
- the calculation module proposed here is connected to the power cell and comprises at least one programmable electronic device, for example a microprocessor (PIC) that applies the method described above to establish V M pp, without interrupting the voltage supply to the user's load network. Additionally, for this function, the calculation module provides storage means, a memory integrated or not in the programmable electronic device, capable of storing the necessary data in the establishment of the VMPP voltage. Said calculation module, which may or may not be integrated in the power conditioning unit, incorporates digital analog converters to receive the measurement points of the electrical characteristic and analog digital converters to deliver the reference voltage to the power cell of said power conditioning unit, which constitute an interface with the solar source.
- PIC microprocessor
- the programmable electronic device which can be a general purpose microprocessor, a digital signal microprocessor (DSP), an application-specific integrated circuit (ASCI), a programmable card (FPGA) or any combination of the above, is responsible for establishing the continuously updated values of the work point of the solar panel or of the equivalent energy source, accessing the real electrical characteristics of the source and obtaining from it, with one, two or at most three measuring points, the voltage in the MPP .
- This voltage is the one used as a reference of the power conditioning unit, which can conventionally have a serial or parallel type converter structure, for example with topologies of known power regulators such as S3R or ASR.
- the manufacturer's data and related to the configuration of the solar panel, together with the measurements of its electrical characteristic, are stored in a memory or database, so that the programmable electronic device can access them and execute the specific calculations and iterative algorithms to solve the nonlinear equations involved in The exposed control procedure.
- the final objective is that the power conditioning unit regulates the voltage of the energy source following the reference signal.

- the calculation module (5) performs three successive operations: i) Identification of the new analytical form i (v) of the electrical characteristic, as the one drawn in Ia Figure 4, which presents the solar source (1), according to the equations:
- the calculation module (5) has at least one microprocessor that processes data from a database and the values of the coordinates of the working point of the solar source (1), to establish the reference voltage (V M pp ) which is Ia of the Point of
- a dependent on the material and temperature of the photovoltaic cells of the source (1), the short-circuit current (i S c) and the current in the dark (i R ) of said source (1), as well as set a value for the current (IMPP) at the Maximum Power Point (MPP).
- the calculation of the first parameter ( ⁇ R), ie, the current in the dark is executed by the microprocessor at the beginning, when the solar cells are new; then, the value of said current in the dark is recalculated or updated periodically and stored in the microprocessor memory as explained below.
- a point (MO) corresponding to the "old" Maximum Power Point (MPP) is indicated, having a single measuring point (M2, M'2) according to if the panel power has increased or decreased.
- MPP Maximum Power Point
- point M2 is to the right of M1, if the current is greater than that of the "old” MPP, and M'2 is located to the left of M'1 otherwise.
- Microprocessor organizes the calculation of the coordinates of the third measurement point (M3, M'3), located at the midpoint of the M1 M2 or M'1 M'2 segment, from which the coordinates of the "new" Point of Maximum Power (MPP).
- M3, M'3 the third measurement point located at the midpoint of the M1 M2 or M'1 M'2 segment, from which the coordinates of the "new" Point of Maximum Power (MPP).
- MPP Point of Maximum Power
- the change in the value of the current causes the microprocessor to receive the instruction to search for the coordinates of the new MPP.
- the coordinates of the solar panel operating point are known at all times by the microprocessor.
- the microprocessor can take as initial value in its calculations of said dark current (i R ), the one obtained from certain data of the manufacturer of the solar source (1), which are: the short-circuit comment in conditions normal pressure and temperature, that is, at an atmosphere and
- the microprocessor calculates in the initialization or the first moment of using the system the value of the dark current (i R ).
- this initial value of the dark current ( ⁇ R ) is entered, as an input of the microprocessor to perform the first calculation of the Maximum Power Point (MPP), this value can be periodically updated, for example, every one hundred calculations of the Point Maximum Power (MPP). Since each search for the Maximum Power Point (MPP) only requires in the worst case three measurement points (Mi, M 2 , M 3 ) of the electrical characteristic of the solar source (1), it is enough to solve the corresponding simple mathematical system to obtain a new value of the current in darkness ( ⁇ R ), such as:
- the periodic update of the value of the current in darkness ( ⁇ R) is carried out, based on the respective coordinates (vi, H), (and 2 ,
- Obtaining the other two parameters basically consists in solving a system of equations with two unknowns, which is achieved by processing in the calculation module (5) the available data of two work points (Mi, M 2 ) of the electrical characteristic, as shown in Figure 6, where the first point (M 1 ) is defined by coordinates (v1, M).
- the voltage (vi) of said first point (M 1 ) corresponds to the "old” or already known value of the voltage at the Maximum Power Point (MPP), that is, at the "old” point (M 0 ), but
- the current (J 1 ) is different from that corresponding to the Maximum Power Point (MPP) because it varies with changing solar lighting conditions. Assuming that this first value of the current (ii) of the first point (Mi) is greater than the value of the current (IMPP) at the Maximum Power Point
- Figure 6 shows a starting point (M 0 ) of the electrical characteristic, whose coordinates are those of the "old MPP” and that moves to M1 (v1, i1) with the change of MPP. Therefore, the "future" value of the Maximum Power Point (MPP), which determines a new point (M 2 ) of the characteristic, is located to the right of the first point (Mi). On the contrary, assuming that the first value of the current (J 1 ) is lower in amplitude that of the "old" Maximum Power Point (MPP), the "future” value is located to the left of the first point (M 0 ) and determines another point (M'-i) of the electrical characteristic. Adding a small positive increase (Av 1 ) to the first voltage (v1) that is serving as a reference to the power conditioning unit (2), the second point (M 2 ) is measured in
- This second point (M 2 ) corresponds to an intermediate point directly in the vicinity of the Maximum Power Point (MPP) or is already the same , obtained according to the sign of the variation between the previous value of the current stored in the memory and the measured value of the current, which when negative can correspond to another second point (M ' 2 ).
- MPP Maximum Power Point
- M ' 2 the second point
- a second equation can be established together with (2.27) to calculate the two parameters (mise, na), or what is the same, the unknown values of the form factor of The characteristic (A) and the short-circuit current (i S c) -
- the computation time that the microprocessor takes to execute this method is of the order of a few hundred microseconds, the above hypothesis can be accepted for that time interval.
- the second measurement point (M 2 , M ' 2 ) that is needed can be taken as the maximum power point established when the value of the short-circuit current (i S c) has not yet been identified, thus approaching the voltage value at said point (v 2 ) by which it gives the following expression:
- the derivative of the expression (2.14) corresponds to obtaining the slope (p) of the line M 1 M 2 , which is tangent to the curve at a third point (M 3 ) of coordinates (V 3 , 3 ) corresponding to the midpoint of the M 1 M 2 segment, that is:
- the microprocessor After determining the value in the working characteristic of the short-circuit current ( ⁇ se), the microprocessor can know the value of the constant (a) simply with the operation:
- the microprocessor can apply the iterative algorithm of
- the calculation at the Maximum Power Point (MPP) of the current ( ⁇ MP P ), translates into obtaining the point of intersection between the curves (fi) and (f 2 ), which is unique and corresponds to the value of current that maximizes in the power function (P) and is the desired Maximum Power Point (MPP), as illustrated in Figure 1.
- the calculation module (5) is able to continuously predict the coordinates (V M p ⁇ , IMPP) > without disturbing the voltage supplied to the user's load network (4), which may consist of a battery bank, a motor or a DC pump, ... This procedure is valid even when the Maximum Power Point (MPP) is modified by environmental changes in lighting, temperature, etc.
- the power conditioning unit (2) regulates, following the reference signal supplied by the calculation module (5) and that it establishes an interface with the solar source and said power conditioning unit (2).
- This independent calculation module (5) delivers in real time to the power cell (3) a voltage value (VMPP) in correspondence, that is, strictly proportional or equal to the instantaneous value of the voltage of the Maximum Power Point (MPP) ) in terms of breadth and transitory.
- the voltage thus regulated is the input voltage of a power cell (3) of the series type or the voltage supplied to the user's network (4) by a power structure of the parallel type.
- FIG. 7 represents the particular case in which the power conditioning unit (2) has a structure of a regulator parallel switched sequential, for example of the known type S3R.
- the basic principle is to make an electronic switch that connected in parallel with a photovoltaic panel works in two ways: in open circuit and in short circuit.
- the S3R regulator insulates the solar panels of the users during a part of the switching period and forces said solar panels, generators of currents (IGSI, IGS2, - -., I GS ⁇ ) to work at a regulated voltage, such as the MPP obtained in this invention.
- the advantage of using the S3R regulator is the minimization of the power dissipated in all switches.
- the solar panel Since these switches have only two operating states, the solar panel will be well short-circuited and, therefore, the short-circuit current (i S c) is automatically known, or, by supplying power to the load network (4) of the users through the diode connected in series.
- the coordinates of the first working point (M1) are also automatically known. And, consequently, all parameters are automatically available when the coordinates of said first working point (M1) are known.
- the S3R regulator can also be applied in a series structure, forcing the solar panels to operate at the reference voltage in the open circuit.
- the form factor of the characteristic (A) can also be obtained directly, since the coordinates of the working point (M1) are known, by means of the formula:
- the directly available data is the open circuit voltage (v oc ) and to know the first working point (M1), it is known that when the series switch is in conduction connecting the solar panel to the users, there is a relationship that links the open circuit voltage (v oc ) with the short-circuit current (i S c) and the constant (a) of the electrical characteristic, which is the following:
- the microprocessor can easily calculate the solution of the system of two equations (2.37) and (2.38) to obtain the first point (M1) of the characteristic of the solar source (1).
- the calculation of the rest of the parameters of the electrical characteristic does not depend on the voltage and current measurements of the second point (M2) to generate the line M1'M2 or M1 "M2" seen in the Figure
- FIG. 8 Another possible topology that can be used to implement the power conditioning unit (2) is the one known as type S4R, represented as a block diagram in Figure 8, with the connection to a battery (6), a control unit of The battery (7) and a battery discharger (8).
- This power conditioning unit (2) of type S4R includes a serial power cell (3 1 ) and a parallel power cell (3 ").
- S4R units (2a, 2b, ..., 2n) can connect following the scheme of Ia
