“…As shown in [7], the quadratic program based on sensitivity is the key for the success of the proof of equivalence. In [27], it is pointed out that the power tariff can substitute the sensitivity to formulate quadratic programs for the DSO and aggregators optimizations. In this paper, a small fixed power tariff (FPT) is employed to formulate quadratic programs (see detailed formulation in Section IV.A).…”

This paper proposes a dynamic tariff-subsidy (DTS) method for congestion management in distribution networks with high penetration of photovoltaics (PV), heat pumps (HPs) and electric vehicles (EVs) with vehicle-to-grid (V2G) function. The DTS method is an extension of the dynamic tariff method proposed in the previous study. With the DTS, the regulation prices can be positive (tariff) or negative (subsidy). The study shows that the negative regulation price is necessary and very effective to solve congestion due to feed-in power flows, such as PVs and EVs in the V2G mode. In the study, dual decomposition of a convex quadratic model is proposed in addition to a conventional method for the DTS calculation. The case studies on the Roy Billinton Test System (RBTS) demonstrate the efficacy of the DTS method for congestion management in distribution networks.

“…In contrast, DERs placed behind the meter are outside of utilities' jurisdiction and therefore can only be indirectly influenced by price signals (e.g. tariffs) to support grid operation [15,16,17]. For example, energy [15] and power [16] based dynamic tariffs can be used to indirectly change the dispatch of EVs in order to alleviate congestion.…”

Similarly, time-differentiated energy prices can be offered to incentivize DR behaviours that impact the reliability of the distribution grid [17].…”

The effect of rate design on power distribution reliability considering adoption of distributed energy resources

Electricity rates are a main driver for adoption of Distributed Energy Resources (DERs) by private consumers. In turn, DERs are a major component of the reliability of energy access in the long run. Defining reliability indices in a paradigm where energy is generated both behind and in front of the meter is part of an ongoing discussion about the future role of utilities and system operators with many regulatory implications. This paper contributes to that discussion by analyzing the effect of rate design on the long term reliability indices of power distribution. A methodology to quantify this effect is proposed and a case study involving photovoltaic (PV) and storage technology adoption in California is presented. Several numerical simulations illustrate how electricity rates affect the grid reliability by altering dispatch and adoption of the DERs. We further document that the impact of rate design on reliability can be very different from the perspective of the utility versus that of the consumers. Our model affirms the positive connection between investments in DERs and the grid reliability and provides an additional tool to policy-makers for improving the reliability of the grid in the long term.
