## 4 Proposal for the Method of Dynamic Differentiation of Electricity Tariffs
Peak power consumption (P): \[P_{w}^{p}(t_{w})\in(P_{w}^{pp},P_{w}^{\max}],P_{h}^{p}(t_{h})\in(P_{h}^{pp},P_ {h}^{\max}],t_{w}=\overline{t_{p_{w}^{pp}}},t_{p_{w}^{\max}},t_{h}=\overline{ t_{p_{w}^{pp}}},t_{h}^{\max},P_{w}(t_{p_{w}^{pp}})=P_{w}^{pp},\] \[P_{h}(t_{p_{w}^{pp}})=P_{h}^{pp},P_{w}(t_{p_{w}^{\max}})=P_{w}^{ \max},P_{h}(t_{p_{h}^{\max}})=P_{h}^{\max}\]
4. A fixed tariff rate is established for the base consumption zone, and an interval of tariff rates is established for the half-peak and peak power consumption zones: 1. Basic power consumption (B): \[C^{B}(t)=C^{B},t=\overline{0,23}\] 2. Half-peak power consumption (PP): \[\overline{P}_{w}=\frac{\sum\limits_{t=0}^{n-1}P_{w}(t)}{n},\overline{P}_{h}=\frac {\sum\limits_{t=0}^{n-1}P_{h}(t)}{n}\]0
5. Peak power consumption (P): \[\overline{P}_{w}=\frac{\sum\limits_{t=0}^{n-1}P_{w}(t)}{n},\overline{P}_{h}=\frac {\sum\limits_{t=0}^{n-1}P_{h}(t)}{n}\]1
6. We believe that the increase or decrease in energy consumption proportionally reduces or increases the cost of electricity in the corresponding zone with the coefficient \(K\):1. Half-peak power consumption (PP): \[\overline{P}_{w}=\frac{\sum\limits_{t=0}^{n-1}P_{w}(t)}{n},\overline{P}_{h}=\frac {\sum\limits_{t=0}^{n-1}P_{h}(t)}{n}\]2 2. Peak power consumption (P): \[\overline{P}_{w}=\frac{\sum\limits_{t=0}^{n-1}P_{w}(t)}{n},\overline{P}_{h}=\frac {\sum\limits_{t=0}^{n-1}P_{h}(t)}{n}\]3
6. The chain growth rates are calculated, which characterize the increments of energy consumption in the areas of half-peak and peak consumption: 1. Half-peak power consumption (PP): \[\overline{P}_{w}=\frac{\sum\limits_{t=0}^{n-1}P_{w}(t)}{n},\overline{P}_{h}=\frac {\sum\limits_{t=0}^{n-1}P_{h}(t)}{n}\]4 2. Peak power consumption (P): \[\overline{P}_{w}=\frac{\sum\limits_{t=0}^{n-1}P_{w}(t)}{n},\overline{P}_{h}=\frac {\sum\limits_{t=0}^{n-1}P_{h}(t)}{n}\]5
7. A dynamic calculation of the cost of electricity for the consumers at each time point for working days and days off are produced. In case of increase in energy consumption in the half-peak and peak zones, an additional penalty is imposed \([G(t)-1]K\). Accordingly, when energy consumption decreases in comparison with the previously registered value, the tariff rate is decreased: \[TC_{w}(t)=\left\{ \begin{array}{l}C^{B}P_{w}(t),P_{w}(t)=P^{\min}_{w}\\ C^{P}(t)P_{w}(t)+[G^{PP}(t)-1]K^{PP},P_{w}(t)\in(P^{\min}_{w},P^{PP}_{w}]\\ C^{P}(t)P_{w}(t)+[G^{P}(t)-1]K^{P},P_{w}(t)\in(P^{PP}_{w},P^{\max}_{w}]\\ \end{array} \right.,\] \[TC_{h}(t)=\left\{ \begin{array}{l}C^{B}P_{h}(t),P_{h}(t)=P^{\min}_{h}\\ C^{PP}(t)P_{h}(t)+[G^{PP}(t)-1]K^{PP},P_{h}(t)\in(P^{\min}_{h},P^{PP}_{h}]\\ C^{P}(t)P_{h}(t)+[G^{P}(t)-1]K^{P},P_{h}(t)\in(P^{PP}_{h},P^{\max}_{h}]\\ \end{array} \right.\]
8. The total cost of electricity per day is calculated, taking into account the discrete values of the indications of smart meters: \[TC^{D}_{w}=\sum_{i=1}^{n}TC_{w}(t_{i})(t_{i}-t_{i-1}),TC^{D}_{h}=\sum_{i=1}^{ n}TC_{h}(t_{i})(t_{i}-t_{i-1})\]  
The above algorithm implements the principle of dynamic pricing of electricity for the consumer, when at each moment in time it is determined in which energy consumption zone (base, half-peak, peak) the consumer load curve is found. Based on the calculation of the chain load growth rates for each energy consumption zone, a system of tariff rates is formed. The growth of energy consumption in the semi-peak zone and its coverage due to the use of energy system resources, rather than renewable energy, is punished by higher tariff rates, reduction of energy consumption is encouraged by a dynamic reduction in rates.
