Abstract:The rapid development of Energy Internet (EI) has prompted numbers of generators to participate, leading to a hybrid power system. Hence, how to plan the hybrid power system and allocate its profit becomes necessary. In this paper, the cooperative game theory is introduced to discuss this problem. We first design the basic structure of EI, and point out the object of this study-coal power plant-wind farm-photovoltaic power station-energy storage provider (CWPE) alliance. Subsequently, average allocation strategy (AAS), capacity-based allocation strategy (CAS) and Shapley value allocation strategy (SAS) are proposed, and then the modified disruption propensity (MDP) index is constructed to judge the advantages and disadvantages of the three schemes. Thirdly, taking a certain area of A Province as an example, the profits of CWPE under three strategies are calculated respectively. Finally, by analyzing individual rationality and collective rationality of cooperative game and the MDP index of the three profit allocation schemes, we find that SAS is the most stable.

“…The ESFs according to the severity levels of the AOSs are reported in Table 2. Total ESF at four RESs is 35.70 (event/year), and the ESF for AOS 4 (A+B+C+D) which all RESs can simultaneously experience voltage sags below the threshold is 2.95 (event/year). This means that the RESs can be simultaneously shutdown about three times per year.…”

“…In the first case, the operation failure of three or more RESs must be prevented. Therefore, the ESS site reducing CESF [3][4] (P k ) for more AOS 3 severity level should be determined. In the second case, the operation failure of all four RESs must be prevented.…”

-This paper proposes a method to utilize an energy storage system (ESS) based on the assessment of an area of severity (AOS) to voltage sag. The AOS is defined as a set of the fault positions that can cause voltage sags at many buses simultaneously. The assessment of AOS helps to determine an optimal location of ESS installation to minimize the expected sag frequency (ESF) at concerned buses. The ESS has the ability not only to play traditionally known roles but also to mitigate voltage sag impact on renewable energy sources (RES) in the islanded microgrid. Accordingly, using the proposed method the ESS has additional features to prevent the operation failure of RESs and improve the stability of the microgrid. In order to verify the presented method, a case study was conducted on the sample microgrid system that is modified from an IEEE 57-bus system.

“…Therefore the energy storage drive control must be tuned to have a slower response than the grid side inverter control. The importance of co-coordinating the control between these two inverters is demonstrated in [5], where lack of coordination between two inverters, both trying to control a DC link voltage leads to instability in the DC link voltage.…”

The fluctuating nature of power generated from waves combined with the weak nature of the network, makes the connection of arrays of wave energy converters (WECs) to the network a challenge. This paper investigates the research questions raised by the proposed development of a wave farm using coastal WECs, where the spatial layout of the WECs is restricted and cannot be used to damp the fluctuations in generated power. The concept of using energy storage on a common DC link to compensate for the fluctuations in real power, and ensure that the power quality on a weak, rural distribution network is not compromised, will also be discussed.
