“…A large number of wind power grids will have a greater impact on the safety and stability of the power system 68‐70 . In addition, the asynchronous generator of the wind turbine absorbs the reactive power from the system when it sends the active power, which causes a certain burden on the power grid 59,71 . These uncontrollable factors render the power load of the wind power generation to be unable to be adjusted in time and effectively, such that the power is difficult to be adjusted as well.…”

Summary Wind energy conversion system, aiming to convert mechanical energy of air flow into electrical energy has been widely concerned in recent decades. According to the installation sites, the wind energy conversion system can be divided into land‐based wind conversion system and offshore wind energy conversion (OWEC) system. Compared to land‐based wind energy technology, although OWEC started later, it has attracted more attentions due to its significant advantages in sufficient wind energy, low wind shear, high power output and low land occupancy rate. In this paper, the principle of wind energy conversion and the development status of offshore wind power in the world are briefly introduced at first. And then, the advantages and disadvantages of several offshore wind energy device (OWED), such as horizontal axis OWED, vertical axis OWED and cross axis OWED are compared. Subsequently, several major constraints, such as complex marine environment, deep‐sea power transmission and expensive cost of equipment installation faced by offshore wind conversion technology are presented and comprehensively analysed. Finally, based on the summary and analysis of some emerging technologies and the current situation of offshore wind energy utilization, the development trend of offshore wind power is envisioned. In the future, it is expected to witness multi‐energy complementary, key component optimization and intelligent control strategy for smooth energy generation of offshore wind power systems.

“…Therefore, the cost of energy is considered as the important measure, since the proposed objective function tries to minimize the energy import and export. Generally, the annualized energy cost for the block rate tariff and ToD tariff are calculated using the Equations (17) and (18), respectively:…”

“…However, to reduce the financial investments, the residential consumers select grid-connected renewable plants to avoid the use of storage facilities. 18 The residential consumers facilitated with EV can use the EV battery as an energy storage when the EV is plugged into the grid for charging. 13,16 Hence, the objective function used for load scheduling should ensure minimum charge-discharge cycles so that the scheduling does not affect the battery life seriously.…”

The utility company enforces a limit on the amount of energy injected into the utility grid from residential renewable plants due to the stability/protection concerns caused by the reverse power flow. Under this scenario, a proper load scheduling at the consumer end is necessary to ensure maximum renewable energy utilization during the surplus generation. This article proposes a novel objective function to impart energy self-sufficiency for residential consumers who own electric vehicles and renewable energy power plants. The proposed objective function aims to promote the consumers to utilize the local sources such as the battery of an electric vehicle, solar PV, wind, etc., effectively through load scheduling. A dedicated program in MATLAB platform is developed for load scheduling, and an experimental case study is conducted using the forecasted demand and generation profiles collected from 10 typical residential consumers. Three new techno-economic parameters namely, aggregate daily exchanged energy, daily average discharged energy, and daily average self-sufficiency hours are proposed to conduct the comparative study. An Average Rank ranking method is introduced to evaluate the effectiveness of the proposed and conventional objective functions statistically. The result analysis proves that load scheduling using the proposed objective function secure the best Average Rank of 2.02 compared to the conventional objective functions.
