Power transfer control within the framework of vehicle-to-house technology

Abstract

<span lang="EN-US">The emerging vehicle-to-grid (V2G) technology has gained a lot of praise in the last few years, following its experimental validation in several countries. As a result, this technology is being investigated for standalone houses under the name of vehicle-to-house (V2H). This latter proposes a two-way power transfer between the electric vehicles and isolated houses relying on renewable sources for power supply. In this paper an implementation of the V2H technology is investigated, using the adaptive backstepping control approach for the bidirectional half-bridge and the integral sliding mode control for the DC-DC converter. The robustness of the controller and its capability to respond to the desired performances were tested using different realistic scenarios. The obtained results yielded, a perfect sinusoidal output voltage with a voltage level of 220 V and a frequency of 50 Hz. This is further been validated by a frequency analysis resulting in a THD of 0.25%.</span>

Dynamic line rating for grid transfer capability optimization in Malaysia

“…q s by IEEE-738 standard was determined based on (10), where Q se is the total radiated heat intensity corrected for elevation, θ is the effective angle of incidence of the sun's rays and A′ is the projected conductor area. In this paper, A′ was assumed to be 0.02862 m. In (11) was used to determine the P s , where I T is the global solar radiation. q s andP s were determined based on (10) and (11), as summarized in Table 3.…”

“…However, the reliance on conservative weather conditions leads to underutilizing of the line's current carrying capacity (ampacity) potential [8]. The SLR is becoming less relevant since it fails to consider climate change, integrating renewable energy sources [9], [10], fast-growing demand [11] and conductor ageing, which can increase the risk of forced blackouts. The dynamic line rating (DLR) concept has emerged as a key solution to address these limitations.…”
